Question

The density of a substance is ${8 g c c}^{- 1}$ . Its specific heat is $1 c a l g^{- 1} C^{- 1}$ . Find its thermal capacity per unit volume.

Open in App

Solution

Thermal capacity, $c = m S$ where $S =$ specific heat
or $c = (ρ V) S$
Thus, thermal capacity per unit volume $= c / V = ρ S = 8 \times 1 = 8 c a l / c c^{o} C$
