Question

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).

Answer 1

Correct Answer: 1200

Under adiabatic conditions, the heat capacity ($C_V$) is calculated using: \[ C_V \times \Delta T = P \times t \] Substituting the values: \[ C_V \times 5 = 60 \times 100 \] \[ C_V = \frac{60 \times 100}{5} = 1200 \, \text{J K}^{-1} \]
