Heat is being supplied at a constant rate to a sphere of ice which is melting at the rate of 0.1 gm/sec. It melts completely in 100 sec . The rate of rise of temperature thereafter will be (Assume no loss of heat)

Options:

Answer:

Solution:

$P = 0.1 \times L_{f}$

$m \times L_{f} = P \times 100$

$P = m \times S_{W} \times (\frac{d θ}{d t})$
