A sample of argon at 2.0 atm pressure is heated until its temperature is raised from 60 °C to 90 °C. The pressure of the gas at this temperature is 3.0 atm and the volume is 4.4 L.

Question

What was the initial volume of the gas?

Answer 1

(P1V1/T1) = (P2V2/T2)
Rember T must be in kelvin.

Answer 2

I have tried these calculations. I believe the answer is 6.1, is this correct?

Answer 3

I agree
