Front

What is buoyancy?

Back

The ability to float in some liquid material.

What happens to a gas when it is heated?

Back

It increases in volume.

Front

What is a fluid?

Back

Any substance that can flow and take the shape of the container that holds it.

Front

What does it mean if an object is neutrally buoyant?

Back

It will neither float nor sink.

Front

Why does a helium balloon float in air?

Back

Helium is less dense than the air.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

What is the principle of buoyancy?

Back

An object will float if it displaces a volume of liquid equal to its weight.

Front

What is an example of a buoyant object?

Back

A rubber duck floating on water.

Front

What is the relationship between density and buoyancy?

Back

Objects with lower density than the fluid will float, while those with higher density will sink.

Front

What happens to the buoyancy of an object as it goes deeper in water?

Back

The buoyancy remains the same, but pressure increases.
