1B) Distinguish between perfectly elastic collision and perfectly inelastic collision. 2a An Iron rod of mass 2kg and at a temperature of 280°C is dropped into some quantity of water initially at a temperature of 30°C. if the temperature of the mixture is 70°C, calculate the mass of the water. (neglect heat losses to the surroundings, SHC of iron=460j/kg/k, SHC of water= 4200j/kg/k).
