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: -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. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.
Detailed explanation-3: -Liquids have an indefinite shape and a definite volume.
Detailed explanation-4: -In gases, the particles are very loosely packed and the intermolecular force of attraction is very weak. So the gas molecules can break loose easily from any boundary and can fill up any space. Hence, they do not have any definite volume. Q.
