When a 60W60W electric heater is immersed in a gas for 100s100s in a constant volume container with adiabatic walls, the temperature of the gas rises by 5°C5 ° C. The heat capacity of the given gas is JK−1{JK}^{- 1} (Nearest integer)

Correct answer

0

Step-by-step solution

Heat capacity=Heat absorbedchange in temperature\text{Heat capacity} = \dfrac{\text{Heat absorbed}}{\text{change in temperature}}

1 Watt = 1 Joule per second

Hence, heat absorbed =60×100J= 60 \times 100J

Change in temperature =5°C= 5 ° C

Heat capacity=60×100J5= \dfrac{60 \times 100J}{5}

=1200JK−1= 1200{JK}^{- 1}
