What are the three states of matter?

solid, volume, mass

density, volume, mass

solid, liquid, gas

density, gas, volume

Adding HEAT to matter causes its particles to:

move faster and farther apart

Move slower and farther apart

Move faster and closer together

Move slower and closer together

When temperature increases (gets "hotter"), the volume of matter increases (gets bigger).

Dissolving

Compression

Thermal Expansion

Diffusion

This picture is an example of...

When thermal energy is added to a substance, the substance's particles move:

More rapidly at an increased distance from each other.

More rapidly with less distance between each other.

More slowly with a greater distance between each other.

More slowly with a reduced distance between each other.

Thermal energy always moves:

From a high temperature object to a lower temperature object.

From a lower temperature object to a higher temperature object.

From an object with lower kinetic energy to an object with higher kinetic energy.

From an object of higher mass to an object of lower mass.
