Created Date: 5/13/2008 3:44:16 PM It's important that we are comparing molecules of roughly the same size here, because if we were a comparing a long hydrocarbon chain without hydrogen bonding to a short chain with hydrogen bonding, it … Long-chain molecules can also wriggle around more freely at a higher temperature and hence disentangle more quickly. The viscosities of some representative liquids are listed in Table 11.3.1 and show a correlation between viscosity and intermolecular forces. Viscosity is expressed in units of the poise (mPa•s); the higher the number, the higher the viscosity. Some of them are necessary (e.g. Marketing cookies are used by third parties or publishers to show you personalized advertising. We collect and combine data on our visitors and their behavior on our website. It is a nonflammable, clear, colorless liquid that is denser than water and has a pleasant etherlike odor. For the remaining liquid metals, very limited literature is available. Chloroform, also called trichloromethane, is an organic compound with the formula CHCl3. Fenghour and Wakeham [32] have presented an explicit model to calculate the viscosity … More commonly used is the dyne sec/cm 2 which is called Poise. Chloroform was once widely used as a solvent, but safety and environmental concerns have reduced this use. The paper contains new measurements of the low-density vicosity of CH 4 (25–200°C), CF 4 (25–600°C) and SF 6 (25–300°C). Use the gas law equation to calculate mol of CH4 in 1 litre under the specified conditions: PV = nRT . 1.5*1.0 = n* 0.082057 * 298 Chloroform - dynamic viscosity over temperature. Nevertheless, chloroform has remained an important industrial chemical. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords.
