Answer

Explanation:

Step1: Recall kinetic - energy formula

The average kinetic energy of a gas particle is given by $K_{avg}=\frac{3}{2}kT$ and also $K_{avg}=\frac{1}{2}mv^{2}$. Since the mass $m$ is the same for both gases and the particles in gas A have a higher average speed $v$, from $K_{avg}=\frac{1}{2}mv^{2}$, gas A has a higher average kinetic energy.

Step2: Recall pressure - kinetic - theory relation

The pressure of a gas is related to the average kinetic energy of its particles. Higher average kinetic energy of particles means more frequent and more forceful collisions with the walls of the container. Since gas A has particles with higher average kinetic energy, gas A has a higher pressure.

Answer:

  1. gas A
  2. gas A
