The viscosity (η) of a gas depends on its mass, effective diameter, and average molecular velocity of the gas. Estimate the effective diameter of the methane molecule (CH4) if the η value for helium is ηHe = 2.0 × 10−5 kg / ms and methane is ηCH4 = 1.1 × 10−5 kg / ms at room temperature, and the effective diameter helium is dHe = 2.1 × 10−10 m!
