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:

c = 14.668 J/kg°C

Step-by-step 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=(Q)/(m\Delta T)\\\\c=(965\ J)/(0.25\ kg* -263.15^(\circ) C)\\\\c=14.668\ J/kg^(\circ) C

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