20. Complete the following:
(a) Solid
Liquid
(b)
Boiling
Gas​

Answer 1

Answer:

Matter can exist in one of three main states: solid, liquid, or gas. ... Particles can move about within a liquid, but they are packed densely enough that volume is maintained. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed.
