buoyancy. the buoyant force of an object is equal to the weight of the fluid being diplaced by the object
pressure is transmitted throughout a fluid
Pressure measured in units called____and most pressure is measured in kilopascals ex atmospheric pressure at sea level cant expand
Gases like air are usually confined to containers. A ____ would be a container that can____.How?
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.
What would happen if you decreased the size of the container?
Increase the pressure-remeber, pressure depends on how often particles collide with the container.
Would the opposite be true?
Yes, if you increase the volume, you decrese the chanced of collision. So you decrease the pressure.
British Scientist_____ put this into a principle which became known as___.
Robert Boyle-Boyle's Law
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."
Another way to look at it is"______"
As pressure decreases volume increses.
