Can you confirm please
Given a cylinder of fixed volume filled with one mole of Ar gas,which of the following is CORRECT?
(assume that all gases obey the ideal gas laws)
A: if the cylinder temp. is changed from 20 to 25 deg.C the pressure will double
B:a cylinder of identical volume filled with the same PRESSURE of He must contain more atoms of gas as He atoms are smaller than Ar atoms.
C:if a second mole of Ar is added to the cylinder, the ratio T/P would remain constant
D: two of the above
E: none of the above
I think its E none of the above..after scouring through the text book for way to many hours I have reached the conclusion that if all the gases obey the same ideal gas law ....then none can be right!!!
Am I correct please in my thoughts?
