Question

The specific heat capacity of copper is three times the specific heat capacity of lead. Equal masses of copper and lead are heated from room temperature to the temperature of boiling water. To achieve, this the amount of heat added to the copper is______times the heat added to lead.

Answer 1

Answer:

Three times

Explanation:

The amount of heat added to a substance when its temperature is increased from T_1 to T_2 is given by

$Q=mc(T_2-T_1)$

c= specific heat capacity

m= mass of the substance

⇒Q∝c

that is if c is increased three times the amount of heat added is also increased three times. Therefore, the amount of heat added to the copper is three times the heat added to lead.
