Heat energy of

184 \mathrm{~kJ}

is given to ice of mass

600 \mathrm{~g}

-12^{\circ} \mathrm{C}

. Specific heat of ice is

2222.3 \mathrm{~J} \mathrm{~kg}^{-}

{ }^{10} \mathrm{C}^{-1}

and latent heat of ice in

336 \mathrm{~kJ} / \mathrm{kg}^{-1}

A. Final temperature of system will be

0^{\circ} \mathrm{C}

.

B. Final temperature of the system will be greater than

0^{\circ} \mathrm{C}

.

C. The final system will have a mixture of ice and water in the ratio of

5: 1

.

D. The final system will have a mixture of ice and water in the ratio of

1: 5

.

E. The final system will have water only.

Choose the correct answer from the options given below:

View answer and explanation

Correct option: B

A and D only

Options A and D are correct because the heat energy is sufficient to raise the ice to 0°C and partially melt it, resulting in a mixture of ice and water in a 5:1 ratio.
