A gas initially at P i = 2.00 atm, T i = 200.0 K, and V i
Question:
A gas initially at Pi = 2.00 atm, Ti = 200.0 K, and Vi = 50.0 mL is in a cylinder that has a movable piston. The cylinder is heated to Tf = 220.0 K and then the piston is pushed down so that the volume of the gas is decreased to Vf = 25.0 mL.
(a) Calculate the final pressure Pf of the gas, leaving all volumes in milliliters for your calculation.
(b) Calculate the final pressure Pf of the gas with all volumes expressed in liters.
(c) When you are doing initial-condition, final-condition problems, must volumes always be in liters?
(d) When you are using the ideal gas equation in the form PV = nRT, volumes must always be in liters (never milliliters or anything else). Why?
Step by Step Answer:
To solve this problem we can use the ideal gas law which relates pressure P volume V temperature T and the number of moles n of a gas PV nRT Where P p...View the full answer
