Answer :
Answer:
7.51 kJ
Explanation:
This question is asking for an amount of heat so you need the answer to be in terms of Joules (J or kJ). The equation to solve this problem is:
Q = mcΔT where Q is heat, m is the mass of copper, c is the specific heat, and ΔT is the change in temperature.
Given:
mass m = 22.8 g
specific heat, c = 0.385 J/g.°C
ΔT = 875°C - 20.0°C
Q = (22.8g)(0.385 J/g C)(875°C - 20.0°C) = 7510 J or 7.51 kJ
