Final answer:
Solids have a definite shape and volume, while liquids have a definite volume but their shape changes. Liquids and gases are both fluids, but gases do not have a definite shape.
Step-by-step explanation:
A solid differs from a liquid in that it has a definite shape and a specific volume, while a liquid has a definite volume but its shape changes depending on the container it is in.
A liquid differs from a gas in that it does not have a definite shape and its molecules are closely packed together, while gas molecules are more spread out and can freely move around.
A liquid is similar to a gas in that both are considered fluids, meaning they can flow and take the shape of their container.
Plasma is a state of matter in which the particles are highly ionized and can conduct electricity. It does not have a definite shape or volume, and is similar to a gas in that its particles are not tightly packed together.
