Yes, state changes are physical, not chemical. You can freeze, thaw,
evaporate and condense water zillions of times, and it will be
chemically unchanged. But if you were to study Physical Chemistry at
the university level, you would be studying the physics behind the
molecular interactions that govern these state changes. There is a
reason why ice melts at a cooler temperature than steel, and you can
demonstrate that using physics.

I didn't go into computers. I went into Photography for many years,
followed by construction. I didn't start working in the computer
field until much later.
