Question

The gas inside of a container exerts `15 Pa` of pressure and is at a temperature of `220 ^o C`. If the temperature of the gas changes to `150 ^oC` with no change in the container's volume, what is the new pressure of the gas?

Answer 1

The new pressure is `13.2 Pa`

Explanation:

Use the gas law,

`P_1/T_1=P_2/T_2`

`P_1=15 Pa`

`T_1=220`ºC`=493K`

`T_2=150`ºC`=423K`

`P_2=15/493*434=13.2 Pa`
