The temperature of an unknown substance weighing 2,500 grams rises by 100°C when 30,000 cal of heat is added to it. What is the specific heat of this substance?

Question

Quizplus · Accepted Answer

The specific heat (c) can be calculated using the formula $c = \frac{q}{m\Delta T}$, where $q$ is the heat added (30,000 cal), $m$ is the mass (2,500 g), and $\Delta T$ is the change in temperature (100°C). Plugging in the values: $c = \frac{30,000}{2,500 \times 100} = 0.12$ cal/g·°C.
