Question

According to ideal gas law, Which of the following is NOT true ?

• A. Gas molecules have no intermolecular forces.
• B. Gas particles are in random motion.
• C. Gas particles have no volume.
• D. The collisions between any two gas particles arc elastic.
• E. The average kinetic energy of the gas molecules is proportional to the temperature in Celsius degrees.

Answer 1

The correct option is E The average kinetic energy of the gas molecules is proportional to the temperature in Celsius degrees.

Average kinetic energy of the gas particles $K_{avg}=\frac{3}{2}{k}_{B}T$ $⟹K_{avg}\propto T$

where $T$ is the temperature of the gas and measured in Kelvin $\left(K\right)$.

Rest of the statements given are true.

Thus statement in option E is false.
