Why does water remain cool in pitcher?
Cooling is caused by evaporation. Some heat energy is utilised during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water.
Why do we store water in Matkas?
We store water in matkas (earthen pots) to keep water cool. It is due to evaporation of water and earthen pots also have small holes so that air can easily pass.
How does the water kept in Matka become cool during summer?
An earthen pot has a large number of tiny pores on its body. Hence, a small amount of water seeps out from these pores a nd gets evaporated from the surface. Hence, the water inside the earthen pot keeps losing heat, thus remaining cool. Thus, water kept in an earthen pot (matka) becomes cool during summer.
Do you think sand is good for making Matkas Why?
We cannot make pots with sand because the particles are so big and rough and they are loosely packed, where as in a clayey soil the particles are closely bounded and they become hard on drying.
Can we drink Matka water in winter?
With its perfect cooling effect, it is gentle on throat and can be easily consumed by people suffering from cold and cough.
How does Matka cool water?
The cooling process works through evaporative cooling. Capillary action causes water to evaporate from the mini-pores in the pot, taking the heat from the water inside, thus making the water inside cooler than the outside temperature.
Why is cooling produced when a liquid evaporates Brainly?
Process of evaporation requires heat and therefore when the heat is absorbed it gives cooling effect. The cooling effect is seen because the heat that are occupying the area is now absorbed.
Why is cooling produced?
Solution: To change liquid into vapours, heat is needed which is taken from surroundings and temperature of the container or body itself falls and cooling is produced.
Which kind of soil is required for making Matkas and Surahis explain?
Clay soil is used for making pottery like the matki and surahi. Clay has so wide and extended information importance from plantation to making vessels. It is the smallest particle, the particles in this soil are tightly packed together with each other with very little or no air space.
How is loamy soil very useful for the crops?
Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots. Adding organic materials to a sandy soil will improve its ability to hold water and nutrients.
