Question

As the temperature in a sample of gas molecules decreases, which

of the other properties of the gas molecules could be caused to
increase or decrease? *
(Please help me)

Answer 1

See Explanation

Step-by-step explanation:

The kinetic energy of gas molecules is related to the temperature of the gas because temperature is a measure of the average kinetic energy of the molecules of a gas hence the lower the temperature of the gas the lower the average kinetic energy of the molecules of the gas.

The volume of a given mass of gas is directly proportional its absolute temperature(Charles's law). Hence, as the temperature of the gas gas decreases, the gas volume also decreases.

The number of gas molecules is totally independent of the temperature of the gas hence it stays the same.

As the temperature decreases, the number of collision of gas particles decreases as the kinetic energy of the gas particles decreases.

The pressure of a given mass of gas is related to the movement of gas particles. Hence, the lower the temperature the lower the pressure of the gas. Pressure and temperature are directly related hence pressure decreases as temperature decreases.
