In fact, the temperature in summer is much higher than that of popsicles. Popsicles melt when they come into contact with air. When it melts, it will absorb a lot of heat from the surrounding air, so that 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 is too cold to hold a lot of water vapor as before. In this case, excess water vapor condenses into small water droplets, forming floating fog droplets, which turn into white water vapor under illumination. So do clouds, fog, rain and snow. After being irradiated by the sun, the water in rivers, lakes and oceans is constantly turned into steam and scattered in the air.

Air containing water vapor rises to a certain height after being heated. When it meets cold air, it will condense into floating droplets. Water vapor near the ground can form small floating water droplets when it is cold. This is fog. So clouds and fog are essentially the same. Under appropriate conditions, the small water droplets in the cloud continue to merge into larger water droplets until the updraft can no longer support them, and they will fall and form rain. In winter, these water droplets will crystallize into snowflakes and float in the sky.

So, where do these small water droplets come from? The answer is water vapor. In hot summer, the air is full of a lot of water vapor, which is invisible to the naked eye. When the ice cream is taken out of the refrigerator, the water vapor around the ice cream will be cold liquefied into small water droplets and become the "white gas" we can see. We usually eat sorbet in summer, the temperature is relatively high, and there is a lot of water in the air, that is, gaseous water, which is invisible under normal circumstances.

When the sorbet is taken out, its temperature is very low. Below zero, water vapor in the air meets sorbet. Due to heat transfer, the temperature decreases and liquefaction occurs. It condenses into small water droplets around the sorbet, which looks like fog, so it gives people the feeling of gas. Gas is water in the air, which forms small water droplets when it is cold. Eating sorbet outdoors in winter in the north won't get angry, because the temperature outside is lower than sorbet. In summer, there is a lot of invisible water vapor in the air outside. When it meets a cold sorbet, it will liquefy into a mist of water droplets and surround it. Because the water droplets are very small, it seems that the sorbet is "transpiration". I hope my answer can help you. If you have different opinions, you can leave comments and learn from each other.
