Front

What is the principle of buoyancy?

Back

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

Front

What is the definition of convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What happens to the density of water as it freezes?

Back

Water expands and becomes less dense when it freezes.

What is the relationship between temperature and density in liquids?

Back

Generally, as temperature increases, density decreases.

Front

What is the formula for calculating the volume of an irregular object using water displacement?

Back

Volume of the object = Final water level - Initial water level.
