Question

When a 60 W electric heater is immersed in a gas for 100 s in a constant volume container with adiabatic walls, the temperature of the gas rises by . Find the heat capacity of the given gas in  (Nearest integer).

Canvas Classes · Accepted Answer

Strategy:
 Relate the electrical energy supplied by the heater to the thermal energy absorbed by the gas using the heat capacity formula at constant volume.

Step 1: Calculate total energy ()
Energy supplied 
.

Step 2: Calculate Heat Capacity ()
Since the container has constant volume and adiabatic walls, all energy supplied goes into increasing the temperature of the gas.
