p/v/t

• less volume -> more collisions -> more pressure
• temp increases -> particles move faster -> more collisions -> more pressure
• ideal gas -> a theoretical perfect gas which all equations work for
• P1V1/T1 = constant -> P2V2/T2
• P1 = start pressure
• V1 = start volume
• T1 = start temperature
• P2 = end pressure
• V2 = end volume
• T2 = end temperature
• in questions, if temp/pressure/vol stays the same -> cancel out of equation
• gas cylinder = fixed size -> doesn't change -> don't need in equation
