air pressure Flashcards
1
Q
what is air pressure caused by?
A
air particles hitting surfaces
2
Q
what happens if you increase the temperature?
A
the air particles have more kinetic energy
3
Q
what happens if you decrease the volume ?
A
the particles will collide more as there is less space
4
Q
how does air pressure change with height?
A
as you increase the air pressure above sea level the air pressure decreases
