Question : 74

Total: 125

^5

J/Kg is

Solution:

Concept:

Heat needed to melt ice is found by multiplying the mass by the specific latent heat of fusion.

Explanation:

The formula for heat absorbed during melting is:

Q = mL

Where

m = 0.2 \, \text{kg}

and

L = 3.4 \times 10^5 \, \text{J/kg}

Substitute the values:

Q = 0.2 \times 3.4 \times 10^5

Q = 6.8 \times 10^4 \, \text{J}

Answer:

The quantity of heat required is

6.8 \times 10^4 \, \text{J}

, which is option A.
