Gases expand more than solids and liquids because,when solids are heated and form liquids and liquids form gases then the state of these is the lightest and most expanded and if more heated will expand faster.

Gases expand more than liquids and solids because gases are made up of solids and liquids only... when solids are heated up liquids are formed and when liquids are heated up gases are formed and thus otherthan gases nothing is formed and they are the lightest and hence expand sooneerr...

as we all know there are three stages ,solid liquid and gaseous
solid state. the molecules in in the solid are packed really tight with no space for the molecules to move
eg can be an ice.. its molecules are packed tightly and are harder
liquid state ..in this molecules are not packed and are loose but not that in the gas.. they can move ..
eg water in glass
gaseos state in this state molecules are very loosly packed and hence occupies a lot of space
eg air
the two reasons of ur ques can be ; one told above and other that heating too makes the air expand
hope helps...

- in solids the molecular arrangement is very close.they r tightly bound to each other.when heated they expand very small amount.
- in liquids molecules are losely packed. when heated they expand more than solids.
- in gases they are very losely packed. therefore when heated they expand a very large amount than solids and liquids.
hope this is useful.

Gases expand more than liquids and solids because the molecules of gases because the molecules of gases are seperated from one another by wide spaces. When gas is heated (heat is a form of energy) its molecules began to vibrate fast and as a result begins to move away from each other.
In the case of liquid they are not allowed much movement becuse molecules are closer to each other than gases.
For solids they expand the least when heated because the molecules are most tightly packed. they keep on vibrating their fixed position.(a reason for solids" heating by conduction rather than convection as in gases and liquids.)

increases more than the volume of a solid or liquid.However, gases that are contained in a fixed volume cannot
expand - and so increases in tempreture in increases in pressure.
