Gas Laws

• Since all flask have same amount of gas, flask 1 has the least pressure
• Since all flask have same amount of gas, flask 2 has the least pressure
• Since all flask have same amount of gas, flask 3 has the least pressure
• Since all flask have same amount of gas, flask 4 has the least pressure

The following factors relatively affect the behavior of gas molecules EXCEPT -

• Pressure

• Gravity

• Volume

• Temperature

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.
