An iron ball of mass

0.2 \mathrm{~kg}

is heated to

100^{\circ} \mathrm{C}

and put into a block at ice at

0^{\circ} \mathrm{C} \,25 \mathrm{~g}

of ice melts. If the latent heat of fusion of ice is

80 \mathrm{~cal} \mathrm{~g}^{-1}

, then the specific heat of iron in

\mathrm{cal} \mathrm{~g}^{-1} \,{}^\circ\mathrm{C}

View answer and explanation

Correct option: B

0.1

Option B (0.1) is correct because the specific heat of iron is calculated by equating the heat lost by the iron ball to the heat gained by the ice during melting.
