1. Solids have a definite<span> volume and </span>shape<span> because particles in a </span>solid<span> vibrate around </span>fixed<span> locations.
2. </span><span>A </span>gas<span> is a substance with no </span>definite volume<span> and no </span>definite<span> shape. </span>Solids have volumes<span> that </span>do not<span> change easily.
3. </span><span>The atoms and molecules in </span>gases<span> are much more spread out than in </span>solids<span>.</span>
