A quantity of ice is heated until the temperature of the heating vessel is . Which of the following constants NOT required to determine the quantity of heat supplied to the vessel?
A. Specific latent heat of vaporization B. Specific heat capacity of ice C. Specific latent heat of fusion D. Specific heat capacity of water
Correct Answer: A
Explanation
Ice from to water at , the process involves three stages i.e Stage 1 heat required to change the ice at to water at heat required to change all the ice to water at heat required to raise the temperature of water at to Hence, specific latent heat of vapourisation is not required here.
