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?

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

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

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

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

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