States of Matter and Density

Front

What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

What is density?

Back

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

Front

How does temperature affect the state of matter?

Back

Increasing temperature can change a solid to a liquid (melting) or a liquid to a gas (evaporation).

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 happens to the particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

What happens to the particles in a liquid?

Back

In a liquid, particles are close together but can move past one another, allowing liquids to flow.

Front

What happens to the particles in a gas?

Back

In a gas, particles are far apart and move freely, filling the container they are in.

Front

What is freezing?

Back

Freezing is the process in which a liquid turns into a solid due to a decrease in temperature.

Front

What is melting?

Back

Melting is the process in which a solid turns into a liquid due to an increase in temperature.

Front

What is evaporation?

Back

Evaporation is the process in which a liquid turns into a gas due to an increase in temperature.
