Example #1 A 2 kg piece of silver is dropped into a hot water bath. The specific heat capacity of silver is J/gºC. If the temperature of the silver increases from 20ºC to 70ºC what is the heat transferred from the bath to the silver?

Example #2 A 1.5 kg block of copper (c = J/gºC) is at a temperature of 22ºC. The block is placed on a hot plate. If the hot plate transfers 200 kJ of energy to the copper, what is the new temperature of the copper?
