Question

Discuss the effect of temperature on the viscosity of gases and liquids.

Answer 1

Hint :In order to answer this question, first we will discuss the effect of temperature on the viscosity of gases and liquids as the viscosity of gases and liquid are different. And then we will also discuss the term viscosity that is affected by the temperature in every state.

Complete Step By Step Answer:
The drag force increases as viscosity increases in gases and decreases in liquids at high temperatures. The Effects of Rising Temperatures The effect of rising temperature on the sphere is that it will slow down in gases and accelerate in liquids.
Viscosity of liquid decreases with an increase in temperature and viscosity of gases increases with an increase in temperature.
The viscosity of a liquid tends to decrease as the temperature rises, but the viscosity of gases rises as the temperature rises. The slower the gas flows, the warmer it is. The faster the liquid runs, the warmer it is.
The fluid for this purpose could be thought of as being made up of numerous tiny layers. These layers stick together due to the molecules' intermolecular forces of attraction. These attractive forces function as frictional forces, which is one of the causes of the fluid's viscosity. Internal friction is a term used to describe viscosity. As a result, each layer blocks the passage of the fluid layer below it.

Note :
The fluid strain rate generated by a given applied shear stress is determined by the viscosity of gases. The cohesive force between liquid molecules and the collision between gas molecules generate viscosity. Molecules in gas have a lot of mobility and minimal cohesion. Molecules interact by clashing with each other as they travel quickly.
