Why do different liquids have different viscosities?

Force between the molecules of liquid is different for different liquids which is known as cohesive force so different liquids have different viscosity.

Explanation:

As we know that force between the molecules of liquid is known as cohesive force.

This cohesive force between different types molecules is different so here the flow of liquid will have different of viscosity.

So here we can say that different type of liquids have different viscosity so the cohesive force will have different values due to internal property of the molecules.

Viscosity is defined as the relative friction force between the layers of liquid that flow with respect to each other and since it is due to cohesive force so more force between molecules will give more viscosity.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
