🤓 Based on our data, we think this question is relevant for Professor Cheng's class at UCR.

We’re being asked to **calculate the amount of energy** released when **0.850 kg of water** is cooled from **123 ˚C to 19.0 ˚C**.

Note that cooling and freezing is an ** exothermic process**, which means q is negative (–).

There are two heats involved in this problem:

1. **q _{1}** which is the heat in cooling 0.850 kg of H

2. **q _{2}** which is the heat in condensing 0.850 kg of H

2. **q _{3}** which is the heat in cooling 0.850 kg of H

We need to solve for each heat individually then add them together to get the final answer.

Based on the thermodynamic properties provided for water, determine the energy change when the temperature of 0.850 kg of water decreased from 123°C to 19.0°C.
