The latent heat of vaporization of ethanol is 200 calories/gram. This means that _____.
a) about 200 calories of heat must be added to 1 gram of ethanol to change its temperature
b) about 200 calories of heat must be added to 1 gram of ethanol to convert it from a solid to a liquid
c) about 200 calories of heat must be added to 1 gram of ethanol to convert it from a liquid to a gas
How do I figure this one out?
