Response:
1. The first step to approach this problem is to recognize that energy gained is equivalent to energy lost. It takes energy in the form of heat to raise the raise the temperature of 30.0 g of water from 23.0 degrees C to 32.6 degrees C. The higher temperature water at 100 degrees C provides this energy required to raise the temperature of water; the mixture of water at two different temperatures forms a solution at 32.6 degrees C (both end up at same temperature). Thus, energy gained by the lower temperature ...
