# The gas inside of a container exerts #12 Pa# of pressure and is at a temperature of #120 ^o C#. If the temperature of the gas changes to #540 ^oK# with no change in the container's volume, what is the new pressure of the gas?

##### 1 Answer

The new pressure is

#### Explanation:

We use the ideal gas law to calculate the change in pressure. The law is written:

In our problem, only the temperature and pressure change - everything else is a constant. So let's gather all of the constant terms on one side of the equation as follows:

We can use this to calculate the unknown pressure:

Rearranging to find

Where we have added 273 to the temperature in Celsius to convert to Kelvin.
