Steam at 100^(@)C is passed into 20 g of water at 10^(@)C . When water axquires a temperature of 80^(@)C , the mass of water present will be [Take specific heat of water 1"cal"g^(-1)c^(-1) latent heat of steam = 540 cal//g^(-1) ]

300 g of water at 25^(@)C is added to 100 g of ice at 0^(@)C . The final temperature of the mixture is

100 g of water is heated from 30^@C to 50^@C . Ignoring the slight expansion of the water, the change in its internal energy is : (specific heat of water is 4184 J kg^(-1) K^(-1) )

50 g of copper is heated to increase its temperature by 10^(@) C. If the same quantity of heat is given to 10 gm of water, the rise in temperdture is (specific heat of copper= 420 JKg^(-1) K^(-1) , specific heat of water = 4200 jkg^(-1) k^(-1))
