from principle of method of mixturesheat lost by water = heat gained by icems ∆T=mice meltedL---(1)here s is specific heat of water =1m is mass of water= 80g (given)∆T is change in temperature= 30-0=300CL is latent heat of fusion of ice =80 calorie g-1 substitute above values in equation (1)80(1)(30)=m(80)mass of ice melted = 30 g
