Question

According to the kinetic molecular theory, the pressure of a gas in a container will increase if the A) number of collisions with the container wall increases. B) number of moles of the gas decreases. C) temperature of the gas decreases D) volume of the container increases.

Answer 1

The answer is A I just took the quiz

Answer 2

Answer: A) number of collisions with the container wall increases.

Explanation: Pressure is defined as the force acting per unit area.

It is caused due to bombardment of gas molecules on the walls of the container.  

Kinetic molecular theory states that:

1. Gases consist of large number of small particles.

2.  Collision between gas particles and between particles and container walls are elastic collisions .

3.  Gas particles are in continuous motion.

4. There are no forces of attraction between gas particles .

5.  The temperature of a gas depends on the average kinetic energy of the particles of the gas.
