A sample of copper absorbs 43.6 kJ of heat, resulting in a temperature rise of 75.0°C, determine the mass (in kg) of the copper sample if the specific heat capacity of copper is 0.385 J/g°C.

Answer:

[tex]m=1510gCu=1.51kgCu[/tex]

Explanation:

Hello,

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

[tex]Q=mCp\Delta T[/tex]

Whereas Q accounts for the heat, m for the mass, Cp for the heat capacity and ΔT the change in the temperature, therefore, the mass turns out:

[tex]m=\frac{Q}{Cp\Delta T}=\frac{43.6kJ}{75.0^oC*0.385J/gCu^oC}*\frac{1000J}{1kJ}\\m=1510gCu=1.51kgCu[/tex]

Best regards.
