Asample of gas in a closed container at a temperature of 100.0°c and 3.0 atm is heated to 300.0°c. what is the pressure of the gas at the higher temperature?

-  4.6 atm.

Solution:- In this problem, the volume is constant and the pressure is changing as the temperature is changed. It's based on Gay-Lussac's law which states that, "At constant volume, pressure of the gas is directly proportional to the kelvin temperature."

The equation used for solving the problems based on this law is:

Where, is initial pressure and is final pressure.

Similarly, is initial temperature and is final temperature.

= 3.0 atm

= 100.0 + 273 = 373 K

= 300.0 + 273 = 573 K

= ?

Let's plug in the values in the equation and solve it for final pressure:

So, the pressure of the gas at higher temperature is 4.6 atm.
