**URGENT: What is the final temperature of the gas in the cylinder A?**

**1. The problem statement, all variables and given/known data**

Two cylinders each contain 0.30 mol of a diatomic gas at 250 K and a pressure of 3.0 atm. Cylinder A expands isothermally and cylinder B expands adiabatically until the pressure of each is 1.0 atm.

What is the final temperature of the gas in the cylinder A?

What is the final temperature of the gas in the cylinder B?

What is the final volume of the gas in the cylinder A?

What is the final volume of the gas in the cylinder B?

**2. Relevant equations**

PV=nRT

**3. The attempt at a solution**

I am actually lost at where to start for this question. It is the last question left, and is due in 40 minutes so my brain is starting to malfunction, lol. Any help would be appreciated.
