A sample of argon gas has a pressure of 1.35 atm at 22.5 °C. Assuming no change in volume, what temperature will the argon reach at a pressure of 3.21 atm?

Answer 1

P1 initial pressure = 1.35 atm

T1 = initial temperature in Kelvin = 22.5 + 273 = 295.5K

P2 = final pressure = 3.21 atm

T2 = final temperature in Kelvin = ?

P1 / T1 = P2 / T2

plug in the numbers and solve for T2. Then subtract 273 to get the answer in degrees C
