149ml bubble of hot gases at 217 degrees celcius and 1.78 atm escapes from an active volcano. What is the temperature, in celcuis, of the gas in the bubble outside the volcano if the new volume of the bubble is 164ml and the pressure is 0.770atm?

Answer 1

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

Answer 2

thank you so much. I was missing a step.
