in an experiment 17 g of ice is used to bring down the temp of 40 g of water at 34degre Celsius to its frezing temp.. the specfc heat capacity of watr is 4.2 j per g per K.. calculate the specfc latent heat of ice..

Heat energy=mass×heat fusion
Heat energy=mass×specific heat×(change in temperature)
Heat stored by water at 34°C=4.2×40×32=5712J
To melt 17 g of ice takes,17×heat of fusion i.e 5712 J
Specific heat of fusion=5712/17=336J/g
