The Namib Desert is one of the oldest and driest deserts in the world. The desert receives less than 10 millimeters of rain each year and produces almost no grass. But the Namib Desert Beetles are still able to live freely in the desert because they have a very clever and efficient way to drink water.
Let's start with the Namib Desert environment. The Namib Desert itself is very peculiar, it relies on the sea, but it is dry and rainy, and it is a veritable coastal desert. At the same time, it is one of the most foggy deserts in the world. This is because the water-filled wind blows from the sea into the land, and the hot and humid air condenses into fog. Fog is a physical phenomenon in which water vapor liquefies when it comes to cold. The principle of fog formation is that when the air is humid and cooled to a certain extent, a part of the water vapor in the air will liquefy and become a small water droplet. These small droplets of water will suspend in the air to form a fog.
The phenomenon of water vapor liquefaction in life is also common. For example, in winter, people emit white gas, in winter, when glasses enter the house, they fog up, they see "white gas" when boiling water, and water droplets outside iced cans. Examples of industrial use of the phenomenon of liquefaction are the liquefaction of gases into liquids, which are convenient for storage and transportation. For example, liquefied natural gas, liquid nitrogen, etc.
The Namib Desert Beetle uses this physical principle to collect moisture in the air and solve the problem of ingesting the necessities of life. Whenever night comes, the beetles will erect their bodies and then turn their backs to the direction of the fog to get water. According to the principle of physics, the water vapor in the air will condense into water droplets when it encounters the surface of an object with a relatively low temperature. In this way, the mist condenses into small water droplets, which then converge into large water droplets. In addition, the beetle's two back covers are covered with a waterproof layer with hemp dots, so that water can flow down the characteristic grooves on its back to the mouth. Beetles are said to drink the equivalent of 40% of their body weight in one night.
Nature is so magical! Natural selection, survival of the fittest, no matter what kind of environment, will always give you a chance to survive and develop.
Guys, do you have any interesting physical phenomena about the change of state of matter? You are welcome to share!
