Answer 1

Answer:

Mean free path:-The mean free path is the distance that a molecule travels between collisions. The mean free path is determined by the criterion that there is one molecule within the "collision tube" that is swept out by a molecular trajectory. The criterion is: λ (N/V) π r2 ≈ 1, where r is the radius of a molecule.

Dalton's law of partial pressure:-

Ptotal = ∑ni=1pi (or) Ptotal = P1 + P2 + P3 + …. + Pn

Ptotal = ∑ni=1pi (or) Ptotal = P1 + P2 + P3 + …. + PnWhere,

Ptotal = ∑ni=1pi (or) Ptotal = P1 + P2 + P3 + …. + PnWhere,Ptotal is the total pressure exerted by the mixture of gases

Ptotal = ∑ni=1pi (or) Ptotal = P1 + P2 + P3 + …. + PnWhere,Ptotal is the total pressure exerted by the mixture of gasesP1, P2,…, Pn are the partial pressures of the gases 1, 2,…, ‘n’ in the mixture of ‘n’ gases
