The viscosities of some representative liquids are listed in Table 11.3.1 and show a correlation between viscosity and intermolecular forces. The viscosity of {xCH4 + (1 – x)C3H8} with x = 0.949 was measured at temperatures between (200 and 423) K and pressures in the range (10 to 31) MPa using a vibrating-wire-viscometer with the wire clamped at both ends and operating in steady-state mode. Abstract. [°C] Dyn. Tabulated values and viscosity units conversion are given below the figures. No garanty for correctness. Chloroform was once widely used as a solvent, but safety and environmental concerns have reduced this use. AddThis use cookies for handling links to social media. Between 200 K and 400 K, we used a two-capillary viscometer to determine eta (gas)/eta (He) with an uncertainty of 0.024 % for H2 and Ar, 0.053 % for CH4, and 0.077 % for Xe.

Long-chain molecules can also wriggle around more freely at a higher temperature and hence disentangle more quickly. As the molecules acquire more energy, they can escape from their mutual traction more readily. Viscosity of Gases The viscosity of a gas can be thought of as a measure of its resistance to flow and is measured in the CGS unit Poise = dyne sec/cm 2.The viscosity of gases near room temperature are in the centiPoise range, so that is a commonly used unit. Methane, colorless, odorless gas that occurs abundantly in nature and as a product of certain human activities. Necessary cookies enable the basic functioning of the website.
