1. Determine the amount of heat required (in calories and joules) to raise 230 g of a liquid from 22°C to 28°C. The specific heat capacity for this liquid is 0.30 calories per gram per degree Celsius.
2. Determine the amount of heat that would need to be removed to freeze the liquid in the previous problem (assuming the liquid is at its freezing temperature). Determine the amount of heat that would need to be added to boil the liquid in the previous problem (assuming the liquid is at its boiling temperature).
