The molecules of the gas are in perpetual motion at a very high velocity.

Example of gas particles. Liquid are close together with no regular arrangement. We said in previous topics that 1mol gas is 224 liter under standard pressure and temperature and 1mol gas contains 602x10 23 moleculesatoms. Substances that exist in the gaseous phase are commonly referred to as gases.

Additionally gas particles can be of different sizes. When two gases are mixed particles of one gas can effortlessly pass through the intermolecular space of the other gas. In -273 diffusion of gases is zero and in nature Kelvin is the unit of temperature and relation between K and 0 C is.

In other words volume and number of particles of gases are directly proportional to each other. As an outcome both the gases get completely and consistently mixed. For example the collisions caused by a gas trapped inside a balloon cause forces to act outwards in all directions giving the balloon its shape.

Find value of 120 0 C in terms of Kelvin. A good example of this is when you fill a tire with air. Gases having equal pressure and temperature have equal number of particles in equal amount of volumes.

Gases exist in several natural forms. Gas vibrate and move freely at high speeds. At low temperature and ordinary pressure they resemble an ideal gas in which the interaction between the particles is negligible and collisions between them are completely elastic.

Starting from absolute zero the theoretical temperature at which atoms or molecules have no thermal energy ie. Gas particles move in random straight-line motion. Imagine you have a sealed container of a fixed-size a constant volume containing a fixed-number of gas particles.
