Question

The energy stored in water formed from ice is:

• A. latent heat of fusion of ice
• B. $80cal{g}^{-1}$
• C. latent heat of boiling
• D. latent heat of fusion of water

Answer 1

Answer: (A), (B)

The correct options are
A latent heat of fusion of ice
B $80cal{g}^{-1}$

The energy stored in water formed from ice is latent heat of fusion of ice. It is 80 cal g${}^{-1}$ or 334 joules g${}^{-1}$. It is the enthalpy change associated with melting of 1 g of ice to water.
