Solution

Q.
When a 60 W electric heater is immersed in a gas for 100s in a constant volume container with adiabatic walls, the temperature of the gas rises by 5°C. The heat capacity of the given gas is ______ J $K^{- 1}$ . (Nearest Integer) [2023]

Ans.
(1200)

$q_{v} = C_{V} Δ T$

$60 \times 100 = C_{V} \times 5$

$C_{V} = {1200 J K}^{- 1}$
