Pressure & Kinetic Energy of a Gas

The initial average kinetic energy of the molecules was E, when a gas sample is at 27∘C27^\circ\text{C}. When the gas is heated to 327∘C327^\circ\text{C}, then the final average kinetic energy will be

Show answer and solution

Answer: (b)

  1. Average KE ∝T\propto T (kelvin).
  2. T1=300T_1 = 300 K, T2=327+273=600T_2 = 327 + 273 = 600 K
  3. E2=E×600300=2EE_2 = E \times \frac{600}{300} = 2E
  4. So the answer is (b) 2E.
