Question

A motor car, with its glass totally closed, is parked directly under the sun. The inside temperature of the car rises very high. Explain why?

Answer 1

Sunlight's infrared rays travel through the window and heat the interior of the vehicle. The heat trapped within boosts the temperature of the interior since the radiation released by the upholstery and other interior sections of the car cannot flow through the glass. This is due to the fact that glass is transparent to infrared radiation from the sun with shorter wavelengths than that released by the interior of the car, which has a longer wavelength and is opaque.
