How does temperature effect the pressure of a gas?

Answer 1

If the volume of the container is not fixed, increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume). This would be the case for a gas inside a piston, or inside a rubber balloon.

If the volume is fixed, then increasing the temperature will increase the pressure, and decreasing the temperature will decrease the pressure. This would be the case for a gas in a closed solid container, like a canister or sealed metal box.

Increasing pressure will cause the gas to contract (reducing the volume), and decreasing the pressure will cause the gas to expand (increasing the volume). Again, this is if the volume is not fixed. If the volume is fixed, then increasing the pressure will increase the temperature, and decreasing the pressure will decrease the temperature.

These concepts are all determined by something called the Ideal Gas Law. To find out more about how this works, see the Related Questions links below this answer.

Gases can also be changed to a liquid or solid if the temperature is too low or the pressure is too high. As an example steam changes to a liquid when it touches a cold object, and nitrogen gas can be converted to liquid nitrogen by compressing it to very high pressures.

Answer 2

If the volume of the container is not fixed, increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume). This would be the case for a gas inside a piston, or inside a rubber balloon.

Answer 3

As temperature increases pressure of the gas increases because when temperature increases the gas expands results in increase in pressure.

Temperature,pressure and volume are so related with gas

As volume increases pressure of gas decreases,

As pressure increases the temperature of the gas increases,

As temperature increases pressure increases,

Answer 4

The combined gas law is:
pV=nRT, where:
p is the pressure, V is the volume, T is the temperature, R is the universal gas constant and n is the number of moles.

Answer 5

When the temperature is warmer, molecules spread out and move around faster. when the molecules are spread out, it decreases density and pressure.

Answer 6

The temperature effects the pressure of gas in different ways. The hotter it is the more gas comes under pressure.
