Question

Your spaceship has docked at a space station above Mars. The temperature inside the space station is a carefully controlled 24 ºC at a pressure of 745 mmHg. A balloon with a volume of 425 mL from inside the space station drifts into the airlock where the temperature is -95 ºC and the pressure is 0.115 atm. What is the final volume, in liters (L), of the balloon, if the amount of gas does not change?

Answer 1

Use (P1V1/T1) = (P2V2/T2)
Don't forget to use T1 and T2 in Kelvin.
Post your work if you get stuck.
