How much heat energy in Joules is required to heat 16.0 g of copper from 23.0 °C to 66.1 °C? Specific heat of Cu = 0.382 J/(g °C)

Question

Quizplus · Accepted Answer

The heat energy required can be calculated using the formula $q = mc\Delta T$, where $q$ is the heat energy, $m$ is the mass of the substance, $c$ is the specific heat capacity, and $\Delta T$ is the change in temperature. For copper, $m = 16.0 \, \text{g}$, $c = 0.382 \, \text{J/(g °C)}$, and $\Delta T = 66.1 °C - 23.0 °C = 43.1 °C$. Thus, $q = 16.0 \, \text{g} \times 0.382 \, \text{J/(g °C)} \times 43.1 °C = 263 \, \text{J}$.
