pressure in liquids Flashcards
1
Q
what is pressure like in liquids?
A
exerted evenly
increases with depth
increases with density
2
Q
what will pressure be like in a water bottle?
A
water in the lowest hole flows with the strongest force- higher pressure caused by the weight of the water above
3
Q
the denser the liquid=
A
the higher the pressure it exerts
4
Q
what does pressure depend on?
A
depth and density
5
Q
what is the formula for pressure?
A
density x gravitational field strength x depth
6
Q
what is pressure measured in?
A
Pa
7
Q
what happens when an object is immersed in a fluid?
A
fluid will exert pressure, squeezing the object
pressure is exerted evenly across the whole surface of the fluid and in all directions
pressure exerted on objects in fluids create forces- these forces act on 90 degrees to the surface
