How viscosity of water and other liquids depend on the temperature and pressure?

Explanation

To understand how the viscosity of water and other liquids depends on temperature and pressure, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Definition of Viscosity**:
- Viscosity is a measure of a fluid's resistance to flow. It arises from the intermolecular forces between the molecules in a liquid. When layers of liquid move relative to each other, these intermolecular forces create resistance, which we perceive as viscosity.

2. **Effect of Temperature on Viscosity**:
