The reason frost forms on windows is due to the dew point and temperatures. The dew point is a temperature at which water in the air will condense into liquid H2O. In this case the H2O has reached the dew point and has actually frozen due to reaching a temperature of or less than 32 degrees Fahrenheit.

Why is there fog inside your house?

Fog inside the house can occur when warm, moist air comes into contact with a cold surface, causing the air to cool and condense into tiny water droplets. This can happen near windows or doors that are poorly insulated, or in areas with high humidity levels. Adequate ventilation and temperature control can help reduce fog inside the house.

Why do brand new car windows fog up inside in cold weather?

Windows fog because the glass is cold and the humidity is high inside the car. It has nothing to do with the age of the car. Try turning the fan up to circulate the air better, and if that doesn't work, turn the AC on -- but turn the heat up so it doesn't get cold. That will do it for sure.
