Ice at -20°C is added to 50 g of water at 40°C. When the temperature of the mixture reaches 0°C, it is found that 20 g of ice is still unmelted. The amount of ice added to the water was close to (Take, specific heat of water = 4.2 J/g/°C specific heat of ice = 21 J/g/°C and heat of fusion of water at 0°C = 334 J/g) (a) 40 g (b) 50 g (c) 60 g (d) 100 g
