a) Calculate the change in temperature if 3.2 x 104 J of heat was added to a 5.0 kg piece of brass with a specific heat capacity of 3.8 x 102 J/kg-C. (3 marks) b) Gary is working on a physics problem in which 100.0 g of water undergoes a phase transition from water to vapour. He comes up with the following answer for the amount of energy in the transition: (0.100 kg) (2.3 x10 (100.0 C) =2.3 x 10? J Is Gary's answer correct? If so, explain. If not, what mistake did Gary make? (2 marks)
