Use the concept of moving molecules (Kinetic Theory) to explain:

a. why the pressure of a gas increases when the temperature increases if the volume of the gas is constant (rigid container).

b. why the volume of a gas in a flexible container increases when temperature increases if the pressure remains constant

c. why the volume of a gas in a flexible container decreases when pressure outside the container increases and the temperature remains constant

d. why the pressure of a gas increases when more molecules are added to the container if both the volume (rigid container) and temperature remain constant

Step 1

Thank you for the question. As your question has more than 3 parts, according to our policy, we are answering the first 3 parts for you. If you need help with any other particular part, please re-post the question and mention the part you need help with.

Step 2

The four assumptions of Kinetic-molecular theory of gases theory are given below:

• Gases are made up of particles like atoms or molecules which randomly move and there will be no attractive forces between them.
• Comparing the space occupied by the gas particles and the space between particles, the former is much smaller than the latter.
• The average kinetic energy of gas particles and the Kelvin temperature is proportional.
• There is an elastic collision between gas particles or with the wall of their container and thus no energy is lost during collision and total kinetic energy of the particles is constant.
Step 3

(a)

The pressure of a gas increases when the temperature increases if the volume of the gas is constant.

The third assumption describes that the average kinetic energy and Kelvin temperature are proportional and thus as temperat...
