Answer:
c = 14.668 J/kg°C
Explanation:
Given that,
Heat added, Q = 965 J
Mass of the sample, m = 0.25 kg
The change in temperature, [tex]\Delta T=10\ K=-263.15^{\circ}C[/tex]
We need to find the specific heat of the copper. The heat required to raise the temperature is given by :
[tex]Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{965\ J}{0.25\ kg\times -263.15^{\circ} C}\\\\c=14.668\ J/kg^{\circ} C[/tex]
So, the specific heat of the copper is 14.668 J/kg°C.
