Answer to Question #290335 in General Chemistry for jovie

Question

Maria said "As temperature increases viscosity decreases" but Elena stated "As temperature increases viscosity increases". Which statement is true? What would happen if you heat a liquid with high viscosity? Explain

Answer 1

Both statements are true,,as temperature increases viscosity decreases liquids while as temperature increases viscosity increases In gases.

The viscosity will decrease when a liquid with high viscosity is heated.This is because the increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.
