Thermal Physics 1 a) Ice at -10 °C is heated and becomes steam at 110 °C. Draw temperature-energy graph to represent this process. Clearly mark the temperature and label phase change taking place during this process. b) How much heat is required to change 1.2 kg of water at 20°C to steam at 100 °C? Take the specific heat capacity of water as 4200 Jkg-10 C- and the specific latent heat of vaporisation as 2257 kJ kg-1. c) 1.95 kJ of heat energy is required to raise the temperature of 500 g of lead from 15 °C to its final temperature of T°C. Taking the specific heat capacity of lead to be 130 Jkg -10C-1, calculate the final temperature of lead.
