Why Does My Cars Windows Keep Steaming Up?
Condensation is the reason why cars steam up inside. When warm, moist air from your breath, body heat, and additional moisture in the car comes into contact with the cold glass of the windscreen, it cools down. This rapid cooling process causes the moisture in the air to condense, resulting in the appearance of condensation on the window.
The formation of condensation on car windows occurs when warm, moist air encounters a cold surface. The water particles present in the air are cooled and transformed into a liquid, which manifests as the visible layer on the inside of your car windows.
Is the temperature inside the car significantly different from the outside temperature?
Experts unanimously agree that the temperature inside a car can increase up to 70 °F (or 40 °C in SI units) higher than the temperature outside, even on cool and cloudy days.
According to the American Veterinary Medical Foundation, when the outside temperature is in the 90s, the temperature inside a car can rise around 20 degrees within just 10 minutes. After an hour, the car's temperature could reach nearly 140 degrees.
