Liquid

A liquid is one of the three common states of matter (the others being solid and gas). It has a definite volume but takes the shape of its container. Liquids have the ability to flow and are relatively incompressible.

Properties of Liquids

1. Definite Volume: Liquids have a fixed volume that does not change, regardless of the shape of the container.

2. Ability to Flow: Liquids can flow and take the shape of the container they are in.

3. Incompressibility: Liquids are difficult to compress, meaning their volume remains relatively constant even under pressure.

4. Surface Tension: Liquids have surface tension, which allows them to form droplets and exhibit behaviors such as capillary action.

5. Viscosity: Liquids vary in their resistance to flow, a property known as viscosity. For example, honey has a higher viscosity than water.

Examples of Liquids

1. Water

2. Milk

3. Juice

4. Oil

5. Vinegar
