Assertion : The viscosity of liquid increases rapidly with rise of temperature.
Reason : Viscosity of a liquid is the property of the liquid by virtue of which it opposes the relative motion amongst its different layers.

Explanation

To solve the given question, we will analyze the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "The viscosity of liquid increases rapidly with rise of temperature."

- **Viscosity and Temperature Relationship**: Generally, for most liquids, viscosity decreases with an increase in temperature. This is because as temperature rises, the kinetic energy of the molecules increases, allowing them to overcome intermolecular forces more easily, thus reducing the resistance to flow (viscosity).
