1a. If 24.028 g of benzene, C6H6, at 9.025 °C absorbs 2.71 kJ of energy in the form of heat, what is the final temperature of the benzene? The specific heat capacity of benzene is 1.72 J/g×K

1b) A 24.952 g sample of metal at 74.21°C is added to 26.608 g of H2O(l) at 12.012°C in an insulated container. The temperature rises to 15.42 °C. Neglecting the heat capacity of the container, what is the specific heat capacity of the metal? The specific heat capacity of H2O(l) is 4.184 J/(g·°C)

1c) What is the difference between both temperatures in Kelvin?
