Asample of a gas in a rigid container has an initial pressure of 1.049 kpa and an initial temperature of 7.39 k. the temperature is increased to 30.70 k. what is the new pressure?

- 4.36 kPa

Solution:- At constant volume, the pressure of the gas is directly proportional to the kelvin temperature.

Where the subscripts 1 and 2 are representing initial and final quantities.

From given data:

= 1.049 kPa

= ?

= 7.39 K

= 30.70 K

For final pressure, the equation could also be rearranged as:

Let's plug in the values in it:

= 4.36 kPa

So, the new pressure of the gas is 4.36 kPa.
