A) How much heat, in kJ, will be absorbed by a 25.0 g piece of aluminum (specific heat = 0.930 J/g･ °C) as it changes temperature from 25.0 °C to 76.0 °C? And B) A 28.5 g piece of gold is heated and then allowed to cool. What is the change in temperature (°C) if the gold releases 0.116 kJ of heat as it cools? The molar heat capacity of gold is 25.4 J/mol･°C.
