If the specific heat of gold is 0.13 J/(g°C), how much heat does it take to raise the temperature of a 1.0-gram piece of gold from 74°C to 99°C?

Question

Quizplus · Accepted Answer

The correct answer is A.The amount of heat required to raise the temperature of a substance is given by the equation Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat, and ΔT is the change in temperature. In this case, we have m = 1.0 g, c = 0.13 J/(g°C), and ΔT = 99°C - 74°C = 25°C. Plugging these values into the equation, we get Q = (1.0 g)(0.13 J/(g°C))(25°C) = 3.3 J.
