ANSWER unlike solids, both liquids and gases can change their shape to fit the container in which they are held. however, gases can also change volume unlike liquids.
Because there is a freezing point, a boiling point so Solids can change into liquids and liquids can change into gases and all over again!!!!!!!!!!!!!!
The intermolecular strength is higher in liquids than in gases.
evaporation
All gases can be caused to change state to liquids. By either cooling, compression or a combination of both, any gas can be liquefied. This change is a physical change, by the way.
Shape
Liquids and gases can change shape without any change in weight.
Gases have the property of indefinite shape and volume, as they expand to fill any container. They also have low density compared to liquids and solids. Gases can be compressed and expand easily when heated.
vaporization
The two states of matter that are considered fluids are liquids and gases. Both have the ability to flow and change shape to fit their containers.
solids cannot be poured , they cannot also change shape unless you bend it , break a bit of it or melt it. liquids can be poured. gases can not be condensed down
Because they both flow and can change shape
