Copper metal has a specific heat of 0.385 J/g·°C.Calculate the amount of heat required to raise the temperature of 22.8 g of Cu from 20.0°C to 875°C.

Question

Quizplus · Accepted Answer

We can use the formula Q = m*c*ΔT, where Q is the heat required, m is the mass of copper, c is the specific heat of copper and ΔT is the change in temperature.
ΔT = 875°C - 20.0°C = 855°C
Q = 22.8 g * 0.385 J/g·°C * 855°C = 7.51 kJ (kilojoules)
Therefore, the correct answer is D.
