What are the physical properties of a gas?

No definite shape or volume, lowest density, can be compressed.

What happens when matter is heated?

The particle gain energy and vibrate more vigorously, they move further apart, this causes the volume of matter to increase.

15

What happens during expansion of matter?

The particle gain energy and vibrate more vigorously, they move further apart, this causes the volume of matter to increase.

15

What happens when matter is cooled?

The particles lose energy and vibrate less vigorously, the particles move closer together causing the colume of matter to decrease.

15

What happens during contraction?

The particles lose energy and vibrate less vigorously, the particles move closer together causing the colume of matter to decrease.
