Question

If the temperature of 1 mole of an ideal gas is increased by 50 C, calculate the change in the kinetic energy of the system.
  1. 6.235 J
  2. 62.32 J
  3. 623.5 J
  4. 6235.0 J


Solution

The correct option is C 623.5 J
Kinetic energy of 1 mole of gas (KE)=32RT, where R is the gas constant and T is the temperature of gas.
Consider the initial temperature of gas to be t C. On heating, the final temperature of gas will be t+50 C
The change in the kinetic energy of the particles on heating: (ΔKE)=32R(t+273+50)32R(t+273)
=32R×50
32×8.314×50
=623.55 J
