Matter and Energy

Which is NOT part of kinetic theory of matter?

• Matter is made of atoms and molecules that are always in motion

• The higher the temperature of a substance, the faster its particles move

• Matter is important and needs to be studied

• At the same temperature, more massive particles move slower than less massive ones
