How are the particles arranged in a solid?

Close together in a fixed, regular arrangement, only vibrating

Why can a gas be compressed easily?

There are large spaces between the particles that can be reduced

A fixed volume but a shape that fits its container

The heat energy is used to overcome forces between particles to change state, not to raise the temperature

A change of state is occurring at constant temperature

The spreading of particles from a region of higher concentration to lower concentration

That particles are in constant motion

Lighter particles move faster on average

A substance made of only one type of atom

It is two or more elements chemically bonded in a fixed ratio, with new properties

In iron sulfide the iron is chemically bonded to sulfur, so it no longer behaves as iron
