Best Answer

Gases spread with in the given volume.Gas molecules always colliding each other and exert certain pressure on the container for certain weight. Means you can fill gas in volume 2 litres under pressure 2kg/cm2 and the same amount of gas if made to occupy 20 litres volume it spreads accordingly to fill 20 litres volume .Buy pressure will no be 2kg/cm2 it will be less

The molecules are widely dispersed, and the level of dispersion determines the mass within a given volume. The level of concentration is reflected by the pressure of the gas.

Why do solids have fixed shape and volume while liquids only have fixed volume and gases neither have fixed volume nor fixed shapes. why?

Simply, Solids have fixed shape and volume because the particles are very , very close to each other . Volume of liquid is the space which is occupied by this liquid, so it's fixed unless you cool this liquid or heat it and it takes the shape of its container As for the gases, the particles are very apart from each other and move freely, so they cannot have a fixed volume or shape and this is due to the attraction force between particles
