1 Thermal Properties Of Matter
A piece of ice (heat capacity = 2100 J kg -1 °C-1 and latent heat = 3.36 × 105J kg -1) of mass m gram is at –5°C at atmospheric pressure. It is given 420 J of heat, so that the ice starts melting. Finally when the ice-water mixture is in equilibrium, it is found that 1 g of ice has melted. Assuming there is no other heat exchange in the process, the value of m is
