A container holds 1.00 L methane gas at 660 torr pressure when the temperature is 22.0 C how much more pressure will the gas exert if the temperature is raised to 44.6 C

Explanation:

Let suppose that gas behaves ideally, the corresponding equation of state is:

Volume and quantity of moles remain constant due to the container, so that final pressure can be found by the following relationship:

the energy to form plasma comes from heat or electricity in the atmosphere!
