Ideal Gases (Jones)

Question 1

Why do gases exert a pressure

Answer 1

Gas particles collide with an object
Each collision enters a force as pressure why Gas= force/area
If there is a total force exerted on an area there must be a pressure Elastic collision

Question 2

What is an elastic collision

Answer 2

A collision does not lose energy or waste it

Question 3

What is newtons real second law

Answer 3

Resultant force applied is directly proportional to the rate of change of momentum

Question 4

Resultant force equation

Answer 4

F=change in momentum/ time(for collisions)
