Gas Laws & Ideal Gas Equation

We have a jar filled with gas characterized by parameters P,V,TP, V, T and another jar B filled with gas having parameters 2P,V4,2T2P, \frac{V}{4}, 2T, where symbols have their usual meaning. The ratio of number of molecules in jar A to those in jar B is

Show answer and solution

Answer: (d)

  1. N∝PVTN \propto \frac{PV}{T}.
  2. NA∝PVTN_A \propto \frac{PV}{T}, NB∝2P⋅V42T=PV4TN_B \propto \frac{2P\cdot\frac{V}{4}}{2T} = \frac{PV}{4T}.
  3. NA:NB=4:1N_A : N_B = 4 : 1.
  4. So the answer is (d) 4:14 : 1.
