Assertion : The viscosity of liquid increases rapidly with rise of temperature. Reason : Viscosity of a liquid is the property of the liquid by virtue of which it opposes the relative motion amongst its different layers. If both assertion and reason are true and the reason is the correct explanation of the assertion.
Generally spoken viscosity of the fluid increases weakly with pressure. For example, increasing pressure from 1 to 50 atm will increase viscosity air only 10 percent. However, temperature has strong effect. Viscosity increases with temperature for gases and decreases with temperature for liquids.
26 cze 2023 · Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid. Liquids whose molecules are polar or can form hydrogen bonds are usually more viscous than similar nonpolar substances.
