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

Options

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

Answer

C

Explanation

Latent heat of fusion of 10 g of water is `10xx80` = 800 cal
Latent heat of vaporisation of 10 g of steam is `10xx540` = 5400 cal
