the cold oil has higher shear stress than hot oil why

explain as much as possible

Solution

In cold oil the intermolecular attractions are more as compared to hot oil which results more shear stress in cold oil than hot oil.

consider an example of ice and water when certain amount of force is acted on the ice and water. the ice experiences low shear area as result of that it is having higher shear stress where as in hot water experiencing more shear area so that less sheaar stress
