Answer :
Final answer:
The amount of heat energy required to raise the temperature of 136 g copper from 15°C to 85 °C is 4462 J.
Explanation:
To calculate the amount of heat energy required to raise the temperature of copper, we can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the copper, c is the specific heat capacity of copper, and ΔT is the change in temperature.
Given that the mass of the copper is 136 g, the specific heat capacity of copper is 0.385 J/g°C, and the change in temperature is 85 - 15 = 70 °C, we can substitute these values into the formula:
Q = (136 g)(0.385 J/g°C)(70 °C) = 4462 J
Therefore, the amount of heat energy required to raise the temperature of 136 g of copper from 15°C to 85 °C is 4462 J.
