Question

The specific latent fusion of ice in SI system:

• A. 336 Jg^-1
• B. 336,000 J kg^-1
• C. 336 Jg^-1 °C^-1
• D. 336,000 Jkg^-1 °C^-1

Answer 1

The correct option is B

336,000 J kg^-1

1. The amount of heat energy required to melt 1 kg of ice at 0 °C to form water at 0 °C is called the specific latent heat of fusion of ice.
2. The specific latent heat of ice is 336,000 J kg^-1

Hence, the correct answer is (B) 336,000 J kg^-1.
