What is the relationship between the number of wall collisions and the pressure?
What is the relationship between the number of wall collisions and the pressure?
Because a huge number of molecules will collide with the wall in a short time, we observe an average force per unit area. These collisions are the source of pressure in a gas. As the number of molecules increases, the number of collisions and thus the pressure increase.
What is the relationship between temperature number of wall collisions and pressure?
The faster these particles are moving when they hit the wall, the greater the force they exert on the wall. Since the force per collision becomes larger as the temperature increases, the pressure of the gas must increase as well.
What is exerted when molecules collide with the walls of their container?
When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.
Which of the following is not an idea in the kinetic molecular theory?
The following statement is not part of the kinetic molecular theory : Attractive and repulsive forces are present between gas molecule. According to the kinetic molecular theory, there is no attractive (or repulsive) force between the molecules, as they move independent of each other.
Which of the following is not true of kinetic energy?
Work and Energy Review
| Description of Physical Situation | +, -, or no Work |

| g. In a physics lab, an applied force is exerted parallel to a plane inclined at 30-degrees in order to displace a cart up the incline. | A. Positive Work |
Which is not an assumption of the kinetic molecular theory?
The correct option is e. Gases do not put any kind of force of attraction or repulsion on the other molecules. So, options a,b,c,d are the assumptions of kinetic molecular theory. But the theory does not relate the speed of the molecule with the pressure value.
