Front 1

Arichimedes(explain)

Back 1

buoyancy. the buoyant force of an object is equal to the weight of the fluid being diplaced by the object

Front 2

Pascal

Back 2

pressure is transmitted throughout a fluid

Front 3

Pressure measured in units called____and most pressure is measured in kilopascals ex atmospheric pressure at sea level cant expand

Back 3

Pascals

Front 4

Gases like air are usually confined to containers. A ____ would be a container that can____.How?

Back 4

Balloon;expand;As the particles collide with the walls of the balloon, it expands. As more air is pumped in, more collisions occur and the balloon expands even more, if it cant expand, it bursts.

Front 5

What would happen if you decreased the size of the container?

Back 5

Increase the pressure-remeber, pressure depends on how often particles collide with the container.

Front 6

Would the opposite be true?

Back 6

Yes, if you increase the volume, you decrese the chanced of collision. So you decrease the pressure.

Front 7

British Scientist_____ put this into a principle which became known as___.

Back 7

Robert Boyle-Boyle's Law

Front 8

Boyles Law states"If you increase the size of a container at the same temperature, the pressure will increase, if you increase the volume at the same temoerature, the pressure will decrease."

Back 8

True

Front 9

Another way to look at it is"______"

Back 9

As pressure decreases volume increses.
