Detailed explanation-1: -Gases have the following characteristics: No definite shape (takes the shape of its container) No definite volume. Particles move in random motion with little or no attraction to each other.
Detailed explanation-2: -Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Detailed explanation-3: -A gas has neither a definite shape nor a definite volume. Like liquids, gases are fluids. The particles in a gas can move around one another freely.
Detailed explanation-4: -A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.
Detailed explanation-5: -Gases do not have a definite shape but they have definite volume.
