If the pressure of a 2.00 L sample of gas is 50.0 kPa, what pressure does the gas exert if its volume is decreased to 20.0 mL? Which equation should you use? StartFraction V subscript 1 over T subscript 1 EndFraction equals StartFraction V subscript 2 over T subscript 2 EndFraction. P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. StartFraction V subscript 1 over n subscript 1 EndFraction equals StartFraction V subscript 2 over n subscript 2 EndFraction.
