Why Does the Car Window Frost Over?

[StRhett]

Frosting on the car window is a phenomenon caused by the condensation of water vapor. Before parking, the temperature inside the car is higher than the outside temperature. The residual warm air inside the car keeps the windows at a certain temperature. Over time, as the interior temperature equalizes with the outside temperature, the warm air on the windows will cause frost to form. If frost appears on the car windows, you can turn on the car's air conditioning before driving to remove the frost using warm air. Alternatively, you can use a spray de-icer, a concentrated liquid specifically developed for frosted car windows. It does not damage the car glass and can prevent further frosting, keeping the windows clean.
