Answer to Question #107535 in Molecular Physics | Thermodynamics for Chia

Question

What is the specific heat capacity if it takes 1000 J of energy to heat 25 g of this substance by 100°C? Give your answer in J/kg°C.

Answer 1

The specific heat capacity

$$c=\frac{Q}{m\Delta T}=\frac{1000\:\rm J}{0.025\:\rm kg\times 100\:\rm ^{\circ}C}=400\:\rm J/(kg ^{\circ}C).$$
