Gases

Gas molecules have no definite ___ or ___, are widely ___ and can be easily ____. They are in ___, constant motion

Atoms which exist in pairs due to unstable nature, and high reaction as a single atom

Temperature is the measure of __ __ or movement of gas particles. Movement increase the ____ and, thus when collisions occurs, there is more energy or ___ transfer.

Gases do not have distinct ___, instead they take up the shape of the container.

pressure is the ___ of the gas particles colliding with the __ of the container. An increase in _____ results in a decrease in pressure

When gas is confined to a container, an external force can compress that gas, and the volume ____. This results in more ____, and thus more ____.

When the gas is expanded, the volume is ___, __ collisions, and __ pressure

The kinetic molecular theory gasses states that particles in a gas are in constant, ____ motion, the combined __ of the particles is negligible, the particles exert no ___ on one another, the gas molecule collisions are completely ___, meaning there are no ___ ___ between the gases, and all gases have the same __ ___ __ at a given temperature.

At ___K the volume of a gas is 0

Gases behave most ideally at __ __, because the gases are far apart, meaning there are less _____ ___, and interactions. It also behaves most ideally at __ ___, as the gas are __ __ and thus there is an decrease in intermolecular forces
