🤓 Based on our data, we think this question is relevant for Professor Campbell's class at Tufts University.

Solution: For the following processes, calculate the change in internal energy of the system and determine whether the process is endothermic or exothermic: (b) A 50-g sample of water is cooled from 30°C to 15°C, thereby losing approximately 3140 J of heat.
