Question

Melissa found that when she added 965 J of energy to a 0.25-kg sample of copper, the temperature of the copper increased by 10 K. What is the specific heat of copper? Show your work.

Answer 1

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, $\Delta T=10\ K=-263.15^{\circ}C$

We need to find the specific heat of the copper. The heat required to raise the temperature is given by :

$Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{965\ J}{0.25\ kg\times -263.15^{\circ} C}\\\\c=14.668\ J/kg^{\circ} C$

So, the specific heat of the copper is 14.668 J/kg°C.
