In the hot summer, the heat is pressing, and it is only comfortable to eat a popsicle! Have you ever noticed that popsicles are still steaming when they come out of the cooler? It's funny, usually only hot things steam out, so why do popsicles steam out?

The temperature in summer is much higher than that of popsicles, and the popsicles melt as soon as they come into contact with the air, and when they melt, they absorb a lot of heat from the surrounding air, causing the temperature of the air to drop. Normally, the air contains a certain amount of water vapor, and due to the sudden drop in temperature, it reaches a state of saturation or supersaturation. In other words, the air around the popsicle is no longer able to contain as much water vapor as it used to contain due to the decrease in temperature.

In this case, the excess water vapor forms tiny droplets, forming clouds of floating mist-like water droplets, which become white vapor when irradiated by light.

The same is true for the formation of clouds, fog, rain, and snow. The water in the rivers, lakes and seas, after being exposed to the sun, constantly turns into water vapor, floating in the air, the air containing water vapor is heated and rises, rises to a certain height, and when it encounters cold air, it condenses into a mass of suspended small water droplets, which is the cloud. The water vapor close to the ground can also form small suspended water droplets when it is cold, which is called fog.

So clouds and fog are essentially the same. Under the right conditions, the small droplets in the cloud merge into large droplets until the rising air flow can no longer support it, and then it falls down to form rain. In winter, these droplets crystallize into snowflakes and flutter all over the sky.

However, the condensation of saturated water vapor in the air must have its "core", which is the dust floating in the air, which is one of the necessary conditions for the formation of clouds, fog, rain and snow.

The secret of the clouds inspired the British physicist Wilson. After research, in 1894 he invented a device called the "cloud chamber", which was filled with clean air and saturated vapor of alcohol (or ether). If an invisible charged particle breaks in, it becomes the core of the condensation of the "cloud", forming fog spots, which show the "footprint" of particle movement.

Therefore, scientists can use the "cloud chamber" to observe the movement and changes of elementary particles (electrons, protons, etc.) that are invisible to the naked eye. At the same time, a number of new elementary particles have been discovered. Wilson's cloud chamber was awarded the Nobel Prize in Physics in 1927 for his outstanding contribution to the study of the microscopic world.
