Q1         Canusing synthetic oil after using conventional oil damage a car 
engine?

A1          Erika Fernandez, Car Lover Mar 14

The short answer is no, using synthetic oil after usingconventional oil will 
not damage a car engine. In fact,it is quite common for car owners to switch 
from conventional to synthetic oilwithout any issues.

Synthetic oilis a type of motor oil that is formulated to provide superior 
lubrication andprotection compared to conventional oil. It is made from a 
combinationof specially designed chemicals and additives that offer a wide 
range ofbenefits, including better engine performance, improved fuel 
efficiency, andincreased longevity of engine components.

On the other hand, conventional oil is made from crudeoil and contains 
impurities that can cause engine deposits, sludge buildup, andpremature wear 
and tear. While it is still a viableoption for older vehicles, modern engines 
are designed to work best withsynthetic oil.

Whenswitching from conventional oil to synthetic oil, the most important thing 
toconsider is the type of oil filter used. Synthetic oil hassmaller molecules 
compared to conventional oil, which can cause it to flow morefreely and 
potentially expose any accumulated dirt and debris in the engine. Therefore, it 
is recommended to use a high-quality oil filter that caneffectively capture and 
remove any contaminants.

Another thing toconsider when switching to synthetic oil is that it may cause 
some leaks in older engines.This is because synthetic oil has a different 
consistency and may flowdifferently through the engine components compared to 
conventional oil.However, this is usuallya temporary issue that can be resolved 
by replacing any worn out seals orgaskets.

So to summarize theanswer, using synthetic oil after using conventional oil 
will not damage a carengine. In fact, it can provide several benefits and 
improve engineperformance. The most important things to consider when making 
the switch arethe type of oil filter used and the potential for temporary leaks 
in olderengines.

Q2         Whatis the history of Tamil Nadu? Was it ever independent? If so, 
what were itsboundaries?

A2          Ravi Chandran, Lives in Chennai, TamilNadu, India (2013–present)4h

The history ofTamil Nadu was very much independent from 300 BC -1300 CE under 
cheras, cholas,Pandyas, Pallavas and Kalabhras.

This 1600 year long independent history is the longestfor any Indian ethnic 
community. There wereseveral invasions from Karnataka, one from Guptas and 
another one from Kalinga.They were short lived and this country quickly 
recovered from the shocks.Tamils also made invasions in all the southern 
states, Kalinga and Bengal. Weresuccessful in Srilanka and south east Asia 
under Pallavas and Cholas.

This long rule was ended by Malikkafur the powerfulKhalji General. He was a 
Hindu convert who nevertasted defeat. The Tamil rule which ended because of his 
attacks ceased toexist as an independent kingdom afterwards.

With the exceptionof Kalabhras all the other Tamil kingdoms have invaded 
outside Tamizhagam.

Peak of cheras,Peakof cholas,Peak of Pandyas:

Peak of pallavas:

Kalabhras were confined to Tamizhagam.

As per ancientTamil literature the boundaries of Tamizhagam were

North Tirupathi,SouthKanyakumari,west Arabian Sea,East Bay of Bengal.This 
apparently includes Kerala also.

Q3         Whichpressure cooker is better, steel or aluminum?

A3          TTK Prestige, appliances and tools canmake meal-planning and 
cooking much Nov 11

Pressure cookersare known to be one of the most versatile cooking vessels you 
can add to yourkitchen. They are known to quicken the process of cooking, 
making it easier toprepare your favourite dishes!

Steel Pressure Cookers Vs. Aluminum Pressure Cookers

If you are lookingto buy either a Steel or Aluminum pressure cooker, here are 
some points thatcan help your purchase decision:

Convenience: Aluminum is lighter and easier tomove around the kitchen. Steel is 
heavier as a material and is, thereforestronger, durable, and more 
long-lasting. Both these materials are easy toclean, easy to maintain and they 
are also scratch-resistant. For a no-messcooking experience, Prestige’s 
innovative Svachh range of Pressure Cookers area must have.

Cooking Process: Because of its composition,Aluminum heats faster, and 
therefore needs less time and cooking gas. But bothSteel and Aluminum pressure 
cookers allow heat to be distributed evenly, makingcooking certain dishes 
quicker and more convenient.



Health & Safety: The Prestige range of Steel andAluminum pressure cookers are 
both healthy and safe to cook in as they comeequipped with expanding rubber 
gaskets that prevent unlocking or removing thelid when contents are under 
pressure and the pressure regulators ensure thepressure doesn't get too high.

Price: Both pressure cooker ranges are also pricednearly the same as they come 
with similar features and benefits.

Which one is right for you?

The purchase ofeither pressure cooker is based on personal preference, budget, 
and range.

If you are abeginner in the kitchen, a steel pressure cooker will allow you 
more time tomulti-task as it takes longer to heat up. Because of thecooking 
time, you can take more precautions against the food burning in thepressure 
cooker.

An aluminum pressure cooker offers alittle added advantage in the lesser time 
it takes to heat and therefore cooksthe food faster. Dueto this, special care 
needs to be taken so that it does not burn the food ifleft over an extended 
period of time.

Prestige offers oneof the widest ranges of pressure cookers online and in 
stores. Here, you canchoose a pressure cooker based on your individual 
preferences and uniquepriorities in the kitchen. Because of Prestige’s 
extensive versatility andconstant innovation to create the best products, you

you and your family.

My note- Comparatively Hindalium/Aluminum  cookers are more convenient , either 
 prestige or Hawkins. The reason for introducingstainless steel is still not 
clear, It may shine a bit more. Not recommending prestige products butfor 
information the QA is selected.

Q6         Whatis the difference between a cooler and an air conditioner? 

A6          Offer Deals24/7,Helpful 5h

Differences betweenair conditioners and cooler

Energy Efficiency: Air conditioners are generallyless energy-efficient than 
coolers. Air conditioners consume more electricity because they use 
compressorsand refrigerants to cool the air. 

In contrast, coolers use a simple motor toblow air over a wet surface. However, 
this efficiency also depends on theclimate in which you are living. 

In a hot and dryclimate, a cooler can be more energy-efficient as it cools the 
air byevaporating water. But in a humid climate, an air conditioner is 
moreenergy-efficient as it not only cools the air but also dehumidifies it.

Cooling Capacity: Air conditioners are more effective in cooling largespaces as 
they have a higher cooling capacity than coolers. Air conditioners can quickly 
lowerthe temperature of a room to the desired level, whereas coolers take 
longer tocool the air as they rely on water evaporation.

Maintenance: Air conditioners require more maintenancethan coolers. The 
refrigerant in an air conditioner needsto be refilled periodically, and the air 
filters need to be cleaned regularly.On the other hand, coolersonly require the 
water pad or sponge to be changed periodically.

Cost: Air conditioners are more expensive thancoolers. The initial cost of an 
air conditioner is higher, and they also costmore to operate. In contrast, 
coolers are relatively cheaper and require lesselectricity to run.

Noise Level: Air conditioners are generally noisierthan coolers. The compressor 
and fans in an air conditioner generate more noisethan a simple motor used in 
coolers.

In conclusion, bothair conditioners and coolers have their own advantages and 
disadvantages. Thechoice between the two depends on your needs, budget, and the 
climate you areliving in. If you live in a dry climate and want an affordable 
andenergy-efficient cooling solution, a cooler can be a good option. If you 
livein a humid climate and want a quick and efficient cooling solution, an 
airconditioner is a better choice.

My note- Air filtering is an important one. Coolersdo not filter air, but blow 
cool air. But cost difference is high.

Q7         Whatis the difference between a cart horse and a shire horse?

A7          Claire Jordan, Degree in biology andfolklore; programmer, shop 
owner, secretary on newspaper8h

Well, they’re bothworking draught horses. Buta Shire horse is a specific breed, 
very tall and strong. In the past they weremainly used for ploughing, and now 
to pull ceremonial brewers’drays, take part in parades etc, and occasionally 
even for tall, heavy humansto ride.

They come in shadesof black, bay, grey or roan, usually with a lot of white on 
the legs and faceand sometimes the belly, and they have large, plate-like 
hooves with a lot offeathering.

A cart-horse is any horse used for pulling carts. It couldbe a specific breed, 
or no breed. It will usuallybe about the same size as a regular riding horse 
but a bit chunkier, and can beany colour. “Cart horse” is traditionally used to 
mean a horse or a human of a rather burly, physically coarse type.

My note- I enjoyed the last line.

Q10               Whichpeople are descendants of the Huns?

A10        TechBis, Softawre Developer, webDeveloper at Freelancers 
(2020–present)8h

The Huns were a nomadic people who originated from CentralAsia and migrated to 
Europe during the 4th and 5th centuries AD.While the Huns did not have a 
well-documented system of record-keeping, and itis difficult to trace their 
direct descendants today.

However, it is believed that some modern-day populations inCentral Asia and 
Eastern Europe may have genetic links to the Huns due tointermarriage and 
mixing with other populations over time.

 Some historians and geneticists suggest that the Huns might havecontributed to 
the gene pool of modern-day Hungarians, Kazakhs, and otherCentral Asian and 
Eastern European groups.
