Protection Of Liquid From Freezing

By Nancy Thomas


Tar is a very important ingredient used in road construction. This ensures that the stones and concrete stick together on the road. Typically like a glue used for making roads. This material solidifies in normal temperature so it is important to keep it liquid state. Earlier we used to constantly keep the tar drums on the fire. Drum heaters provide perfect solution against liquid freezing.

Solar water heaters were one of the important inventions in the recent times. In hilly areas it is very difficult to get fuel, dry wood or have power lines. This device helped in solving all the related problems mentioned. They also have the provision for storing heat through thermal collector other than water.

Storage water heaters are the most common electrical appliance used in households. It has two outlets inlet and outlet for water flow. The thermostat regulates the heat and cutoff the power if the temperature rises. Everyday this device helps us to take hot shower.

The instant water heaters are a revolution in the wet insulation and storage technology. Firstly it is not bulky as its predecessor. This device is very light and compact. Secondly there is no chance of accidents as it does not store water. Like the old principle the water instantly gets hot while flowing through the copper insulation tube.

Storing water in heights has a different application. The elevation generates high pressure which allows the water to flow through shower and taps. One advantage is we can limit water usage. As water is not stagnant in pots and buckets it will not allow diseases to spread.

Drinking water is the most important thing for mans survival. People cannot live with salt water which is plentiful in the earth. We are dumping garbage, plastic and other industrial waste in the rivers. This has created shortage of water across the globe. Every living being will be extinct from the planet without fresh water. We must take a step forward to preserve our natural resources.

Heat from the fire or sunlight is very important for the survival of humans. The fire has allowed man to live in cold climate also protected them from wild animals. This invention has also taught man to cook and eat processed food. Always the colder climate areas have lower population compared to the tropical places. During winters we do not get enough sunlight which is not good for health.

Every living being has a temperature. This is because the food that we eat is converted into energy. The body needs heat for performing physical and metabolic activities. There are also living organisms which are usually under sea or ocean has lower temperature. They are known as cold blooded animals. Mammals are under sea creatures which have higher temperature.

Air, fire and water these three elements are very important for the survival of living things on this planet. The source of these things is the sun, atmosphere and rivers. Hence is it essential for not to pollute the air or water we drink.
