Popsicle temperature bar solar terms

Have a popsicle! The popsicle was still steaming when it was taken out of the refrigerator! Usually only hot things steam, so why do popsicles steam? Let's explore why popsicles steam!

The temperature in summer is much higher than that of popsicles. Popsicle will melt when it meets air, and when it melts, it will absorb a lot of heat from the surrounding air, so the temperature of the air will drop. Usually the air contains a certain amount of water vapor, which is saturated or supersaturated due to the sudden drop of temperature. In other words, the air around the popsicle can't hold as much water vapor as it used to because of the temperature drop. In this case, the excess water vapor will form tiny water droplets and form a floating water droplet cloud, which will turn into white water vapor after being irradiated by light.

It turns out that clouds, fog, rain and snow are also formed in this way. The water in rivers, lakes and seas, after being irradiated by sunlight, constantly turns into steam and floats in the air. Air containing steam is heated and rises to a certain height. When it meets cold air, it will liquefy the cloud of suspended water droplets. This is the cloud. When the weather is cold, the water vapor near the ground can form a cloud of suspended water droplets. This is fog. So clouds and fog are essentially the same. Under the right conditions, the small water droplets in the cloud continue to merge into large water droplets until the rising airflow can't hold down, and then fall down to form rain. If it is winter, these water droplets will crystallize into snowflakes and fly all over the sky. However, the condensation of saturated water vapor in the air must have its condensation "core", that is, dust floating in the air, which is one of the necessary conditions to promote the formation of clouds, fog, rain and snow.

Ice cream is delicious in summer. The main ingredient of ice cream is ice. When ice melts, it absorbs a lot of heat from the surrounding air, which makes the surrounding environment cold. The water vapor in the surrounding environment condenses and liquefies into liquid water when it is cold, forming "white vapor" around the ice cream.
