Question

The thermal capacity of a solid is \[\frac{400 \mathrm{~J}}{\mathrm{~K}}\]. The amount of heat supplied to it will be ______ if its temperature rises by 40 K.

Options

• 16000 J

• 1600 J

• 1000 J

• none of these

Answer 1

The thermal capacity of a solid is \[\frac{400 \mathrm{~J}}{\mathrm{~K}}\]. The amount of heat supplied to it will be 16000 J if its temperature rises by 40 K.

Explanation:

Heat supplied = Thermal capacity × Rise in temperature

$$Q = C'\Delta T$$

= 400 × 40

= 16000 J
