Properties of matter

When a phase change is occurring, the temperature does not increase because:

• no heat energy is being added

• the heat energy is being used to separate out the molecules

• heat is being removed from the system

In a phase change diagram , which parts show potential energy increasing?

• the diagonal lines that are increasing

• the vertical lines that are flat

• the horizonal lines that are flat

In a phase change diagram, which parts show kinetic energy increasing?

• The diagonal lines are increasing

• the horizonal lines are flat

• the vertical lines are flat

What state of matter affects the pressure in a system?

• solid

• liquid

• gas

Particles that move faster will have NOT have

• a higher kinetic energy

• a higher temperature

• a higher density

• a higher pressure in a gas state

Decreasing the volume of a gas will

• increase the pressure

• decrease the temperature

• decrease the pressure

• decrease the speed of the particles

The amount of particles (mass) is a specific space (volume)

• pressure

• density

• temperature

The force of gas particles colliding with the walls of the container:

• density

• temperature

• pressure

The average kinetic energy of all particles in a substance:

• density

• pressure

• temperature

What type of energy is associated with movement?

• kinetic

• potential
