Water has the following thermodynamic constants: (1) specific heat liquid = 4.18 J/g °C, solid = 2.09 J/g °C, gas = 1.89 J/g °C, (2) heat of fusion = 334 J/g, and (3) heat of vaporization = 2257 J/g.

For a sample of water at 1.0 atm of pressure, mass = 320 g at an initial temperature of -20 °C and a final temperature of 340 °C, answer the following questions:

1. how much heat is required to warm the solid sample to its melting point?

J

2. how much heat is required to melt the sample?

J

3. how much heat is required to warm the liquid sample to its boiling point?

J

4. how much heat is required to vaporize the sample?

J

5. how much heat is required to warm the gaseous sample to its final temperature?

J

6. and finally, how much heat is required for the entire process to occur?
