Copper metal has a specific heat of 0.385 J/g·°C. Calculate the amount of heat required to...
Homework Answers
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.
Q = (22.8g)(0.385 J/g C)(875C - 20.0C) = 7510 J or 7.51 kJ
