A 1.1 kg block of ice is initially at a temperature of -5°C. (a) If 5.3 ✕ 105 J of heat are added to the ice, what is the final temperature of the system? °C (b) Suppose the amount of heat added to the ice block is increased by a factor of 1.3. By what factor must the mass of the ice be increased if the system is to have the same final temperature?
