What is the latent heat of fusion and latent heat of vapourisation of 10 g of ice and water respectively?

Options

A. 800 cal, 800 cal
B. 540 cal, 540 cal
C. 800 cal, 5400 cal
D. 540 cal, 800 cal

Answer

C

Explanation

Latent heat of fusion of 10 g of ice is `10 xx 80` = 800 cal
Latent heat of vapourization of 10 g of water is `10 xx 540` = 5400 cal
