1. On a hot day, the temperature of a 72,000 L swimming pool increases by 1.90°C. What is the net heat transfer (in J) during this heating? Ignore any complications, such as loss of water by evaporation. (Enter the magnitude.)

2. To sterilize a 53.0 g glass baby bottle, we must raise its temperature from 21.0°C to 94.0°C. How much heat transfer (in J) is required?

150 grams of boiling water (temperature 100°C, heat capacity 4.2 J/gram/K) are poured into an aluminum pan whose mass is 970 grams and initial temperature 25°C (the heat capacity of aluminum is 0.9 J/gram/K). (a) After a short time, what is the temperature of the water? (b) What simplifying assumptions did you have to make? The thermal energy of the aluminum doesn't change. Energy transfer between the system (water plus pan) and the surroundings was negligible during this time. The...
