A 150.0-g sample of copper is heated to
Interpretation:
The specific heat of copper is to be determined.
Concept Introduction:
Specific heat of a substance is defined as the amount of heat required to raise the temperature of
Answer to Problem 126QP
Solution:
The specific heat of copper is found to be
Explanation of Solution
Given Information: Mass of copper and water is
Heat transfer takes place from high temperature to low temperature. So, the temperature of copper will decrease and that of water will increase to attain thermal equilibrium. At thermal equilibrium, temperature of both copper and water will be equal.
The heat lost by the copper can be calculated as follows.
Here,
Substitute
Substitute
The heat gained by the water can be calculated as follows.
Here,
Substitute
Substitute
As no heat is lost from the water, according to the law of conservation of energy, the total heat of the system remains conserved.
The specific heat of the copper can be calculated using the above equation and the calculated values of
Therefore, the specific heat of the copper is
The specific heat of the copper is
