How much heat is required to raise the temperature of a 5.75-g sample of iron (specific heat = 0.450 J/g°C)from 25.0°C to 79.8°C?

Question

Quizplus · Accepted Answer

The amount of heat required can be calculated using the formula $q = mc\Delta T$, where $q$ is the heat absorbed or released, $m$ is the mass of the substance, $c$ is the specific heat capacity, and $\Delta T$ is the change in temperature. Plugging in the given values: $q = 5.75 \, \text{g} \times 0.450 \, \text{J/g°C} \times (79.8°C - 25.0°C) = 142 \, \text{J}$.
