Determine the amount of heat required to raise the temperature of a 153 g bar of gold by 50.0°C (specific heat of gold = 0.128 J g^-1 °C^-1).

Question

Quizplus · Accepted Answer

The amount of heat required can be calculated using the formula $q = mc\Delta T$, where $m = 153 \, \text{g}$, $c = 0.128 \, \text{J/g°C}$, and $\Delta T = 50.0°C$. Thus, $q = 153 \times 0.128 \times 50 = 979.2 \, \text{J}$, which rounds to 979 J.
