Pressure Flashcards
(3 cards)
1
Q
How does compresses air cause pressure on the inside of the cylinder?
A
The air particles collide with the walls of the can
-pressure is force on an area
2
Q
Explain what happens to compressed air in a cylinder when the temperature increases
A
Increase in average speed/ kinetic energy of particles
Pressure increases
Particles collide with the walls more often
3
Q
Define pressure
A
Average force per unit cross sectional area for a force acting on a surface at right angles to the surface.
