How much heat is evolved when a 35.0 g sample of copper increases from 25.0ºC to 35.5ºC?

Question

Quizplus · Accepted Answer

The heat evolved can be calculated using the formula $q = mc\Delta T$, where $q$ is the heat evolved, $m$ is the mass of the substance, $c$ is the specific heat capacity of the substance, and $\Delta T$ is the change in temperature. For copper, $c = 0.385 \, \text{J/g}^\circ\text{C}$, $m = 35.0 \, \text{g}$, and $\Delta T = 35.5^\circ\text{C} - 25.0^\circ\text{C} = 10.5^\circ\text{C}$. Thus, $q = 35.0 \, \text{g} \times 0.385 \, \text{J/g}^\circ\text{C} \times 10.5^\circ\text{C} = 139.7 \, \text{J}$.
