The windows freeze in winter because of condensation, and there are snowflakes in winter.

In most parts of the north, the temperature will be very low in winter. Air conditioning or heating is turned on at home, and the door is closed.

When they float to the glass window, they will condense when they touch the cold glass. Snowflake, also known as silver millet, jade dragon and jade dust, is a kind of crystal, which is formed by solid precipitation of condensed water vapor in the sky. Its structure changes with the change of temperature, mostly hexagonal, like a flower. There are many shapes of snowflakes, and each snowflake is an extremely beautiful pattern.
