Final answer:

To raise the temperature of 25 grams of copper by 15°C, 115 J of heat is required.


Step-by-step explanation:

To determine the amount of heat required to raise the temperature of a substance, we can use the equation: Q = m * c * ΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

In this case, the mass of copper is 25 grams. The specific heat capacity of copper is 0.39 J/g·°C. The change in temperature is 15°C. Plugging these values into the equation: Q = 25 g * 0.39 J/g·°C * 15°C = 115 J.
