Question

Why can gae change volume?A. The ga particle have no ma, o they can change volume. B. Gravity ha no effect on ga particle, o they can float away. C. There are no force holding the ga particle together. D. The force holding the ga particle together are tronger than gravity

Answer 1

The gases changes its volume because there are no force holding the gas molecules together. Hence the option C is correct.

Gases do not have a definite shape or volume because the molecules in the gases are very loosely packed, they have large intermolecular spaces , hence they move around. The force of attraction between the molecules is also very less, as a result gases acquire any shape or any volume. In comparison to liquids and solids, intermolecular interactions between gas particle are weaker. Because the atoms in gases are loosely connected to one another, they can move more quickly than those in liquids. Thus, gases lack both a defined shape and a defined volume. They merely assume a container-like shape.

So,  gas molecules can break loose easily from any boundary and can fill  any space. Hence, they do not contain any definite volume.
