These two deal with changing state to a gas. The first involves a
liquid; the latter can be either a liquid or a solid. The main
difference is mostly colloquial; the the former is mostly a passive
action, while the latter implies that energy was deliberately applied
to effect the change.

This is the direct change of state from a solid to a gas without
passing through a liquid state. The most common example of it is dry
ice, or frozen carbon dioxide, which at room temperature and
atmospheric pressure will not become liquid as it turns from a solid
to a gas.
