You have to use the combined gas law. (V1)(P1) / T1 = (V2)(P2) / T2 AND YOU PLUG YOUR GIVEN INTO THE EQUATION. (1910ML)(740TORR) / -22.8 = (V2)(740TORR) / 285DEGREES AND SOLVE FOR V2.

Is it because at high pressure, molecules have volume, and at low temperature gases move slowly and act like a liqud so they have attractive forces that decrease pressure?
