Question 53-54

 

 

 

A sample of a gas in a sealed, rigid cylinder with a movable piston has a volume of 0.250L at STP.

 

53 Show the correct numerical setup for calculating the volume of this sample of gas at 298 K and 1.00atm

Answer-->  PV/T =PV/T  STP = 1atm and 273 K

(1.00 atm x 0.250L)/ 273K = (1.00 atm   V)/ 298K

or since pressure is constant  V/T=V/T

(0.250L)/ 273K = (V)/ 298K

54 State the change in pressure that will cause the gas in the cylinder to behave more like an ideal gas.

Answer--> decrease the pressure
