What are the properties of a gas?

Best Answers

Properties of Gases: 1. A gas has no definite shape or volume of its own. It acquires the shape of the container. Reason: Intermolecular attraction is the weakest in gases whereas intermolecular separation is the largest. Hence, molecules in a gas move very fast and the gas expands to fill all the space available. 2. A gas has no surface of its own. read more

Besides pressure, denoted in equations as P, gases have other measurable properties: temperature (T), volume (V) and number of particles, which is expressed in a mole number (n or mol). In work involving gas temperature, the Kelvin scale is often used. read more

Gases have no definite shape or volume.The random movement of gas molecules allows them to expand or contract to assume the volume of the container holding them. Therefore, a gas's volume refers to the space of the container in which its molecules have range to move. read more
