**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: 1200**

**Solution:**The heat capacity of the gas can be calculated using the formula:

Given data:

- Power of the heater = 60 W (or 60 J/s)
- Time the heater is on = 100 s
- Temperature rise of the gas = 5°C

Now, let’s calculate the total energy emitted:

Total energy emitted = Power × Time

Total energy emitted = 60 J/s × 100 s = 6000 J
