Question

The specific latent heat of fusion of ice in SI system is:

• A. $80cal{g}^{-1}$
• B. $336\times {10}^{3}Jk{g}^{-1}$
• C. $2260\times {10}^{3}Jk{g}^{-1}$
• D. $336Jk{g}^{-1}$

Answer 1

The correct option is B

$336\times {10}^{3}Jk{g}^{-1}$

The explanation for Correct option:

(b) $336\times {10}^{3}Jk{g}^{-1}$

1. Specific latent heat of fusion of ice is the amount of heat energy that is required to melt a unit mass of ice into liquid at zero degrees Celcius.
2. To convert a unit kilogram of ice into water requires $336000J$heat energy.
3. This process is done at a temperature of $0^{°}C$.

Hence, the correct answer is an option (b) $336\times {10}^{3}Jk{g}^{-1}$
