When the temperature of an ideal gas is increased at constant pressure, — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

mean free path is λ = 1 / (√2 π d^2 n*), where n* = n/v = p / k_b t. at constant pressure, as temperature increases, number density n* decreases. because λ is inversely ∝ n*, the mean free path λ increases.
