Two small spherical balls of the same mass, made of copper and of lead are heated up to the same temperature and are placed on a thick wax slab. What will happen and what can we conclude from it?

Text Solution

Verified by Experts

The copper ball sinks in the wax slab more than the lead ball does, because the rate of melting of wax due to the copper ball is greater. From this we conclude that the heat loss of the copper ball is greater than that of the lead ball. But, the mass and the decrease in temperature of both the balls are equal. Therefore, from the equation H = mst we conclude, the specific heat (s) of copper is higher.
