What determines kinetic energy of gases?

Answer 1

Gas particles are so small in relation to the distances between them that their individual volumes can be assumed to be insignificant. The large relative distances between the gas particles means that there is considerable empty space between the particles. This assumption that gas particles are far apart explains the important property of gas compressibility: A gas is easily compressed because of the space between the particles. Therefore, the energy of a collision is absorbed when the gas particles are forced closer together.

The second property of gas particles assumed by the kinetic theory is that no attractive or repulsive forces exist between the particles. As a result, gases are free to move inside their containers. In fact, a gas expands until it takes the shape and volume of its container.

The third assumption is that gas particles move rapidly in constant random motion. The particles travel in straight paths and move independently of each other. Only when a particle collides with another particle or object does it deviate from its straight line path. Kinetic theory assumes further that these collisions between gas particles are perfectly elastic, which means that during a collision the total amount of kinetic energy remains constant and that the kinetic energy is transferred without loss from one particle to another. You should also recall that the average kinetic energy of a collection of gas particles in directly proportional to the Kelvin temperature of the gas.

Answer 2

Heat and pressure. the more pressure we put on a gaseous substance the greater the heat. the greater the heat the more kinetic energy it has.

Answer 3

This is the permanent motion of molecules and depends on temperature.

Answer 4

temperature
