What would happen to the average kinetic energy of the molecules of a gas sample if the temperature of the sample increased from 20ºc to 40ºc?

The answer to this question would be: it would be increase

The kinetic energy of a molecule is influenced by the temperature. In this case, the temperature is increased from 20ºc to 40ºc so its kinetic energy would be increased. The increases won't be too big since the temperature used in the formula is Kelvin, not Celcius.

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
