no definite shape and no definite volume
B

D
motion
Explanation: 

Detailed explanation-1: -Answer: Solution : 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-2: -Due to the weak internuclear force of attraction, the gaseous particles have enough kinetic energy and they can move in any direction without any restrictions. Hence, the gases do not have a fixed shape and fixed volume.

Detailed explanation-3: -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.

Detailed explanation-4: -Gases do not have a definite shape but they have definite volume.

Detailed explanation-5: -A gas has a definite mass but no definite volume and shape.
