Pressure between gases

Question 1

The more __ the particles make, the higher the pressure. Fill in the blank.

Answer 1

collisions

Question 2

What refers to the “collisions” of particles in this topic?

Answer 2

The collisions of particles refers to particles colliding with each other or colliding into a surface/wall.

Question 3

The pressure inside the container and outside the container has to be what?

Answer 3

Equal

Question 4

What are the three main factors that influence pressure?

Answer 4

1. The number of particles
2. Temperature
3. Volume of the container

Question 5

If the number of the particles in a container is high, then the pressure is …

Answer 5

also high.

Question 6

If the number of particles in a container is low, then the pressure is …

Answer 6

also low.

Question 7

When particles inside a container are heated…

Answer 7

When particles inside a container are heated, they expand and gain energy, enlarging the number of collisions and increasing pressure inside.

Question 8

When particles inside a container are cooled…

Answer 8

When particles inside a container are cooled, they contract and lose energy, reducing collisions and decreasing pressure inside.

Question 9

If the volume of the container is small…

Answer 9

If the volume of the container is small, the number of collisions get bigger, increasing pressure.

Question 10

If the volume of the container is large…

Answer 10

If the volume of the container is large, the number of collisions get smaller, decreasing pressure.
