why is a car parked in the sun with windows closed found to be hotter inside than outside

When a car is parked in the sun with its windows closed, it can become significantly hotter inside than outside. This happens due to the greenhouse effect, which occurs when sunlight enters the car and is absorbed by its surfaces, including the dashboard, seats, and steering wheel. As these surfaces heat up, they emit infrared radiation, which is trapped inside the car by the windows and cannot escape.
