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?

Okay, thank you.

a block of aluminum weighing 140. g is cooled from 98.4 c to 62.2 c with the release of 1080 joules of heat. from this data, calculate the specific heat of aluminum

What amount of heat is required to raise the temperature of 20 grams of water from 10°C to 30°C? The specific heat of water is 4.18 J/g°C.Select one of the options below as your answer: A. 1200 joules B. 1500 joules C. 2000 joules D. 2300 joules E. 3000 joules
