P2.1.3 States of Matter (T/F)

Heating or cooling a substance can cause it to change state.

Atoms and molecules are the particles that make up matter.

The pressure of a gas is calculated as the force it applies divided by the area it acts upon.

Solids can easily change shape and volume.

Liquids cannot be compressed easily.

Gases have a fixed volume that does not depend on the container they are in.

The particles in a solid are stationary and do not move.

Liquids have a random arrangement of particles that are closely packed together.

The volume of a liquid is determined by the volume of space occupied by its particles.

Gas particles move at slow speeds and have a regular pattern.

Increasing the temperature of a solid does not affect the vibration of its particles.

In liquids, the forces between particles prevent them from moving around freely.

Solids can flow easily because their particles can move freely.

Solids can change their shape and volume easily when temperature changes.

Liquids assume the shape of the container they occupy.

Gases cannot be compressed or expanded easily.

The volume of a gas is determined by the container it is in.

As temperature increases, the motion of atoms in a substance increases.

It is easier to compress a gas than a liquid because gases have less free space between particles.

Electrostatic forces play a significant role in the properties of gases.

The process of a solid changing to a liquid is known as condensation.

The volume of a liquid changes significantly with temperature.

The arrangement of particles in a gas is regular and closely packed.

Liquids cannot flow because their particles are locked in place.

Pressure in gases results from the particles colliding with the container walls.
