Ideal Gas Equation

Given:

• Initial pressure atm
• Initial temperature K
• Final temperature K
• Volume remains constant

Objective: Find the final pressure .

Using the combined gas law: Rearranging to solve for :

Substituting the given values:

Note: The calculated pressure atm does not match any of the provided options. The stated correct answer is D. 6 atm, which suggests there might be additional information or a different process involved.
