How much heat energy would be needed to raise the temperature of a 22.3 g sample of aluminum [(C = 0.895 (J/g°C)] from 22.5°C to 55.0°C?

Question

Quizplus · Accepted Answer

The heat energy ($q$) required can be calculated using the formula $q = mc\Delta T$, where $m = 22.3 \, \text{g}$ (mass of aluminum), $c = 0.895 \, \text{J/g°C}$ (specific heat capacity of aluminum), and $\Delta T = 55.0°C - 22.5°C = 32.5°C$ (change in temperature). Plugging these values in, we get $q = 22.3 \times 0.895 \times 32.5 \approx 649 \, \text{J}$.
