Two gases of equal mass are in thermal equilibrium. If ${P_a},\,{P_b}$ and ${V_a}$ and ${V_b}$ are their respective pressures and volumes, then which relation is true
  • A${P_a} \ne {P_b};\,{V_a} = {V_b}$
  • B${P_a} = {P_b};\,{V_a} \ne {V_b}$
  • C$\frac{{{P_a}}}{{{V_a}}} = \frac{{{P_b}}}{{{V_b}}}$
  • D${P_a}{V_a} = {P_b}{V_b}$
