Solution: How much energy would be absorbed or released by the H 2O in the process.30 grams H2O(g) at 100°C → 30 grams H2O(l) at 20°C?1. 16.2 kcal absorbed2. 16.2 kcal released3. There would be no transfer of energy due to the first law of thermodynamics4. 18.6 kcal released5. 2.4 kcal released

How much energy would be absorbed or released by the H _{2}O in the process.

30 grams H_{2}O(g) at 100°C → 30 grams H_{2}O(*l*) at 20°C?

1. 16.2 kcal absorbed

2. 16.2 kcal released

3. There would be no transfer of energy due to the first law of thermodynamics

4. 18.6 kcal released

5. 2.4 kcal released
