Why Does the Car Window Freeze on the Inside?

[Keith]

The reason the car window freezes on the inside is due to the temperature difference between the inside and outside of the car, which causes water vapor to form inside the car. When the temperature inside the car gradually drops to match the outside temperature, the water vapor on the window freezes. To reduce or prevent frost and ice from forming on the inside of the window, you can open the car doors for a few minutes before closing them, allowing the interior temperature to equalize with the outside temperature before locking the car. Methods to remove ice from the inside of the car window: 1. Turn on the car's heater to melt the ice layer. First, start the vehicle and wait until the water temperature rises to a certain level, then turn on the interior heater, directing the airflow toward the front windshield. Once the ice has melted, wipe it clean with a dry cloth. 2. Use a de-icing spray to remove the ice. Special de-icing sprays can be used to melt the ice on the front windshield without causing scratches.
