Agas sample enclosed in a rigid metal container at room temperature (20.0∘c) has an absolute pressure p1. the container is immersed in hot water until it warms to 40.0∘c. what is the new absolute pressure p2? express your answer in terms of p1.

Answer : The new absolute pressure is,

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

or,

where,

= initial pressure of gas

= final pressure of gas

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get:

Therefore, the new absolute pressure is,
