Question

What is the heat needed to raise the temperature of 24.7 kg silver from 14.0 degrees Celsius to 30.0 degrees Celsius? Specific heat capacity of silver is 236 J/(kg * C°)

Answer 1

Answer:

$Q=93.3kJ$

Explanation:

Hello,

In this case, by knowing that the heat due to a change of temperature is given by:

$Q=mCp\Delta T$

Whereas Q accounts for the heat, m for the mass, Cp the heat capacity and ΔT for the change in temperature. In such a way the required heat results:

$Q=24.7kg*236\frac{J}{kg^oC}*(30.0-14.0)^oC*\frac{1kJ}{1000J} \\Q=93.3kJ$

Best regards.
