The pressure of gas decreases with increasing temperature?

Answer 1

If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.

Answer 2

It doesn't. All else being equal pressurising a gas increases its temperature. This is because energy has to be expended on the gas to increase its pressure, and this energy increases the average energy per molecule and hence temperature.

Answer 3

It doesn't, pressure of a gas decreases as temperature decreases. Pressure is directly proportional to the absolute temperature. Pressure of gas decreases when temperature decreases because the decrease in temperature causes a decreases in the kinetic energy of the molecules. This decreases in KE causes a decrease in collisions between the molecules which results in a decline in the pressure.

Answer 4

The Ideal Gas Law states that PV=NkT. When the numbers represented by N (the number of gas particles) and k ( a constant) remain the same either the pressure or the volume of the gas must change. If the volume of the container does not decrease then the gas will give up energy in the form of heat.

Answer 5

When the temperature of a gas increases, the average kinetic energy of its molecules also increases. This increased kinetic energy causes the gas molecules to move faster and collide with the container walls more frequently, resulting in an increase in pressure. So, the pressure of a gas increases with increasing temperature, not decreases.
