Heat and Thermodynamics question

2010 · Shift 1 · Q64

JEE AdvancedPhysicsHeat and ThermodynamicsNumerical+3 / −1
A piece of ice (heat capacity = 2100 J kg-1 oC-1 and latent heat = 3.36 ×\times× 105 J kg-1 ) of mass m grams is at - 5 oC 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 gm of ice has melted. Assuming there is no other heat exchange in the process, the value of m is
