Question

Assertion: water flows faster than honey.
Reason: The coefficient of the viscosity of water is less than honey.
A) Both assertion and reason are true and reason is correct explanation of assertion.
B) Both assertion and reason are true but reason is not the correct explanation of assertion.
C) Assertion is true but reason is false.
D) Both assertion and reason are false.

Answer 1

Hint: in this question, we have to understand the viscosity of the fluid is higher in which intermolecular forces are more. If the liquid has less intermolecular force results in less viscosity of the liquid. So, the velocity of the flowing fluid is inversely proportional to the coefficient of viscosity.

Complete answer:
For solving this question we need to know what viscosity and which factors affect the viscosity. The viscosity corresponds to the thickness of the fluid. The resistance between the layers of the fluid which are in contact with each other is referred to as the viscosity of the fluid means viscosity provides resistance. So, we can say that the intermolecular force decides the viscosity of the fluid.
In water, there are only water molecules present, so the attraction or intermolecular force between the molecules is not much high. In honey, many types of molecules are present such as sugars, water, minerals and enzymes, and many other molecules. so, the intermolecular force between the molecules of honey is more. Due to more intermolecular force honey is more viscous than water.
Hence, the coefficient of viscosity of water is less than honey. So, water flows faster than honey.

Therefore, both assertion and reason are true and reason is the correct explanation of assertion is the correct answer which is mentioned in option A.

Note:
Here we must know the principle of viscosity, which is defined as when liquid is subjected to move upon a surface or we can say another layer of the same liquid, the fluid particles tend to oppose such moments. This resisting force developed by a liquid is called viscosity.
