The specific heat capacity of solid copper metal is 0.385 J/gK.How many joules of heat are needed to raise the temperature of a 1.15-kg block of copper from 25.0°C to 66.0°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 the block, c is the specific heat capacity of copper, and ΔT is the change in temperature.

Substituting the given values, we get:
Q = 1.15 kg * 0.385 J/gK * (66.0°C - 25.0°C)
Q = 1.82 × 10^4 J

Therefore, the answer is choice C.

The Specific Heat Capacity of Solid Copper Metal Is 0
