Pressure and Gas Flashcards
1
Q
how does the reduction of volume affect pressure?
A
reducing the volume of a fixed mass of gas increases the pressrue
2
Q
how does pressure increase?
A
- temperature increases
- speed increases
- collisions occur more often and with more force
3
Q
how is kinetic energy affected with gas particle collisions?
A
no kinetic energy is lost when gas particles collide together or with the container
4
Q
example of gases working
A
- pump air into a ball
- the air gets hot because as the piston moves the particle bounce off increases KE, which causes a temperature rise
