Fluids Test

Front

What does Pascal's principle state about pressure changes in an enclosed fluid?

Back

Changes in pressure at any point in an enclosed fluid are transmitted to all points in the fluid.

Front

What is the main difference between a solid and a liquid?

Back

A solid has a definite shape and volume, while a liquid has a definite volume but takes the shape of its container.

Front

What happens to a cruise ship as it is unloaded at port?

Back

The cruise ship floats higher.

Front

What occurs when an object with a density less than that of water is placed in water?

Back

It floats.

Front

Does the buoyant force on a submerged object change with depth?

Back

No, the buoyant force remains constant regardless of depth.

Front

Define buoyancy.

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is the formula for calculating buoyant force?

Back

Buoyant Force = Weight of the fluid displaced by the object.

Front

Explain the concept of density.

Back

Density is the mass of an object divided by its volume (Density = Mass/Volume).

Front

What happens to the density of an object if it is compressed?

Back

The density of the object increases if its mass remains constant and its volume decreases.

Front

What is the relationship between pressure and depth in a fluid?

Back

Pressure increases with depth in a fluid due to the weight of the fluid above.
