Why does laziness start coming after sitting for some time in the sun?
Why does laziness start coming after sitting for some time in the sun?


The heat of the sun is very comfortable in winter, especially after eating food in winter, everyone wants to lie down in the sun for a while and relax. After eating, the blood is used to digest food and the blood sent to the brain is also used in this work, due to which laziness comes. If a person stands for a while in the scorching sun, then all the necessary substances will come out of his body in the form of sweat and that person will fall unconscious.

If the door of the fridge is opened by turning on the fridge in the closed room, is the room warm?

In fact, opening the door of the fridge in a closed room does not make any significant difference in temperature. The reason for this is very simple. There is a mesh device in the back of the fridge which acts as heat radiation. From the open door of the fridge from where we get coolness. The heat from the back of the fridge also emits in the same proportion. When the fridge cools from the room with its open door, the back of the fridge in the same proportion leaves heat in the room. Here the same principle of heat is applied according to which the amount of heat absorbed by an object is equal. Therefore, the room will not be hot but its temperature remains the same.

How does a spider make a net and from where does it get a thread?


The spider extracts a type of silk thread from its body called 'spider silk' to weave its net. This silky invisible thread is made of protein and is produced in spider silk glands. There are seven types of silk glands in the spider class. All spiders have at least three types of glands. Each type of gland has different types of silk. Some kathis produce liquid silk which dries out when the spider comes out of the body and in some it forms sticky silk which remains sticky. 'Spider silk' does not dissolve in water and is the strongest fiber among known natural fibers.

Spinrates are found inside the body of the spider, which weaves silk, acts like fingers of the hand. The spider can pull a spinrate in. Can even push all spinrates out at once. With the help of different spinratos, the spider can make a very thin, thick or wide banded silk by mixing silk produced from different silk glands.

Some spiders make a sticky fiber that looks like a beads of beads. Some spiders have a special type of organ for weaving silk called 'Kryzelam'. It is an elliptical flat plate mounted on the spinnerets. There are hundreds of spinning tubes on this plate which make a very fine filament of sticky silk.

4: - Why does it feel cold on touching immediately after the cycle of the cycle is broken?

Why does it feel cold on touching immediately after the cycle of the cycle is broken?


The bicycle tube is filled with air at high pressure. When the air of the tube expands, it is acted upon by the air, thereby reducing its internal energy and decreasing the temperature of the air. So, immediately after the tube bursts, she feels cold when she touches it.

5: - The moon shrinks, increases and even hides someday, why so?

The moon shrinks, increases and even hides someday, why so?


In fact, the moon does not shrink, grow or hide. Only when we look at it from the earth, it appears. The moon itself is not a light satellite but illuminated by the sun, it reflects that light onto the earth. Due to the changing position of the Sun, Moon and Earth, only a part of the illuminated moon is reflected on the Earth. The occurrence and rise of the moon also appears to us due to this reason.

When the moon revolves around the earth, when we cannot see the whole part of the illuminated moon together. When the moon is between the earth and the sun, the illuminated part of the moon is on the other side of the earth. In this situation the moon is not visible from the earth at all. Which we call Amavasya. When the illuminated part of the moon gradually starts to appear and after 14 days of Amavasya, the earth comes between the moon and the sun. Then we can see the whole illuminated part of the moon.

6: - Why does the shot of the gun become hot when it hits the target?

Why does the shot of the gun become hot when it hits the target?
Why does the shot of the gun become hot when it hits the target?


When the shot of a shotgun hits the target, it has more kinetic energy before it hits the target, but its velocity and kinetic energy becomes zero as soon as it hits the target. For this reason, the shot of the gun becomes hot after hitting the target.

7: - The blanket that keeps us warm in winter also protects the snow from melting, why?

The blanket that keeps us warm in winter also protects the snow from melting, why?
The blanket that keeps us warm in winter also protects the snow from melting, why?


The blanket is made of wool. There is air between its fibers. Air is a bad conductor of heat, due to which the heat of our body does not get out and the blanket keeps us warm. The air between the blanket fibers does not allow the atmospheric heat to enter the air and prevent the ice from melting.

8: - When we rub our hands together, they get hot but why only to a maximum temperature?

When we rub our hands together, they get hot but why only to a maximum temperature?
When we rub our hands together, they get hot but why only to a maximum temperature?


When we rub our hands together, the work done in the rubbing turns into heat, but after some time, when the temperature of the hands becomes equal to a certain temperature, the more heat is obtained by rubbing the hands, the more heat is released out of the atmosphere. It goes into it, hence the heat does not increase further.

9: - In the basement, it feels cold and nice during the day, while there is discomfort in the night?

In the basement, it feels cold and nice during the day, while there is discomfort in the night?
In the basement, it feels cold and nice during the day, while there is discomfort in the night?


Since sun rays do not reach the basement. That is why the basement is not very hot during the day, due to which there is no heat in the day. During the night, the heat of the earth keeps the atmosphere of the basement as warm for a longer time, which is why the rest of the basement feels restless at night.

10: - What is the reason that the water of the wells is cool in summer and why it is hot in winter?

What is the reason that the water of the wells is cool in summer and why it is hot in winter?
What is the reason that the water of the wells is cool in summer and why it is hot in winter?


Earth is a bad conductor of heat. That is why in summer, the atmospheric heat cannot enter the earth and the earth remains cold from inside. Due to which the water of the well remains cold. Similarly, during the winter season, the heat of the earth does not come out and the soil inside remains warm. Due to which the water of the wells remains hot.
