gas particle motion and tempreture

Question 1

What is gas pressure?

Answer 1

the pressure of gas is due to the particles colliding with the walls of the container that the gas is held in. By colliding with the walls of the container the gas particles are exerting a pressure.

Question 2

how can we increase gas pressure?

Answer 2

•by increasing the amount of collisions per second
•by increasing the energy of collisions

Question 3

what is temperature?

Answer 3

The average kinetic energy of particles in a substance

Question 4

Is gas pressure high or low at low temperatures?

Answer 4

At lower temperatures, particles have lower kinetic energy so there are fewer collisions per second. These are lower energy collisions

Question 5

is gas pressure high or low at high temperatures?

Answer 5

At high temperatures particles have higher kinetic energy. These are more collisions per second and are higher energy collisions
