Front

How do molecules in a gas behave compared to those in a liquid?

Back

Molecules in a gas can move more freely and are not tightly packed, while molecules in a liquid are closer together and can slide past each other.

Front

What is the ability to flow?

Back

It is a property of both gases and liquids that allows them to take the shape of their container.

Front

Which state of matter has the highest kinetic energy?

Back

Gas.

Front

What is the arrangement of particles in a gas?

Back

Particles in a gas are far apart and move freely.

Front

What is the difference between solids, liquids, and gases in terms of shape and volume?

Back

Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases have neither fixed shape nor volume.

Front

What happens to the particles in a gas when heated?

Back

They gain kinetic energy and move faster.

Front

What is compressibility?

Back

The ability of a substance to decrease in volume under pressure, which is a property of gases.

Front

What is a liquid?

Back

A state of matter that has a fixed volume but takes the shape of its container.
