Pressure and Fluid Flashcardziz

Front

What happens to pressure in a fluid when pressure is applied in a closed container?

Back

The pressure increases by the same amount everywhere in the container.

Front

Which has a greater density: 500 grams of styrofoam or 500 grams of silver?

Back

500 grams of silver has a greater density than 500 grams of styrofoam.

Front

What principle states that when pressure is applied to a fluid in a closed container, the pressure increases by the same amount everywhere?

Back

Pascal's Principle.

Front

True or False: Buoyant force acts in all directions.

Back

False. Buoyant force acts upwards.

Front

True or False: The buoyant force is greater than the weight of a helium balloon.

Back

True.

Front

What is the definition of buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object immersed in it.

Front

What is Pascal's Principle?

Back

Pascal's Principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all parts of the fluid.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the density of the fluid it is in.

Front

What is Archimedes' Principle?

Back

Archimedes' Principle states that the upward buoyant force on a submerged object is equal to the weight of the fluid that the object displaces.

Front

What is Bernoulli's Principle?

Back

Bernoulli's Principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.
