Answer the question briefly and the point:
What are the properties of an ideal liquid ?

Explanation

To answer the question about the properties of an ideal liquid, we can summarize the key points as follows:

1. **Incompressibility**: An ideal liquid is incompressible, meaning that its density remains constant throughout its volume. This implies that the liquid does not change its volume or density when subjected to pressure.

2. **Non-viscosity**: An ideal liquid is non-viscous, which means there are no internal frictional forces (tangential forces) acting between the layers of the liquid. As a result, the flow of the liquid is smooth, and there are no energy losses due to viscosity.

In summary, the two main properties of an ideal liquid are:
- It is incompressible.
