Question

A student placed 700 g of water at 28 C in a freezer. After 6 minutes and 15 seconds the water was transformed to ice.

Calculate:

i)the heat energy transferred from the water during the temperature change

ii)the latent heat of solidification, given that 235200 J of heat energy was transferred during the change of state.

iii)the rate of heat energy transfer for the entire process.

[ Specific heat capacity of water = 4200 J kg-1 K-1]
