62. Given a cylinder of fixed volume filled with 1 mol of argon gas, which of the following is correct?
(Assume all gases obey the ideal gas law.)
(A) If the temperature of the cylinder is changed from 25°C to 50°C, the pressure inside the
cylinder will remain the same.
(B) If a second mole of argon is added to the cylinder, the ratio of T/P would decrease.
(C) A cylinder of identical volume filled with the same pressure of helium must contain more
atoms of gas, because helium has a smaller atomic radius than argon.
(D) Two of the above.
(E) None of the above.
