The specific heat capacity of solid copper metal is 0.385 J/g-K. How many joules of heat are needed to raise the temperature of a 2.12-kg block of copper from 25.0 °C to 99.9 °C?

Question

Quizplus · Accepted Answer

We can use the formula:

Q = m c ΔT

where Q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Plugging in the values, we get:

Q = (2.12 kg)(0.385 J/g-K)(99.9 °C - 25.0 °C) 
Q = 6.11 × 10^4 J

Therefore, the answer is (C).

The Specific Heat Capacity of Solid Copper Metal Is 0
