Physical Properties of Water. जल के भौतिक गुण। 

The physical properties of water are as follows -

1. It has the ability to hold cold and heat and can also transfer its coolness and heat. This quality of water has been used in the field of medicine.

2. Water is transparent, so aquatic plants can survive in it because they get sunlight. It is able to absorb only the powerful ultraviolet rays to some extent.

3. The density of water varies with its temperature; It increases when the temperature drops, but the maximum density is at 4 °C, and not at zero °C, as we would expect. Therefore seas and lakes freeze from the surface and do not freeze from the bottom; Where condensate water accumulates by stratification.

4. Water in the solid state is lighter than liquid water.

5. The physical state of water depends on temperature and pressure. The liquid-gas route is traditionally performed at 100 °C at normal pressure at 72 °C only at the top of Everest (8 m). The melting temperature of ice decreases with pressure. The ice again becomes liquid under the influence of a pressure. Because of this, skaters actually slide over a thin film of liquid water formed under the impact of the skate.

6. One of the main properties of water is cleansing. It has the ability to wash the stool and cleans the body. For this reason, the impurities and faeces located in the body are easily removed through water.

7. Water has a positive effect on the cells of the body and increases the efficiency and efficiency of the cells. With the use of water, the cells of the body start performing their functions well. For this reason, taking a bath with water gives a feeling of freshness and energy. The use of water makes the internal organs healthy. By using this, the organs like stomach, intestines, liver, kidney, spleen etc. become healthy. The use of water also purifies the blood.
