Physical Properties of Matter Review

Front

What is density and how does it affect whether substances float or sink in a liquid?

Back

Density is the mass of a substance divided by its volume. Substances with lower density than the liquid will float, while those with higher density will sink.

Back

The three main states of matter are solid, liquid, and gas.

Back

The principle of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the object's density relative to the fluid.
