The heat inside a car

The reason a car without cold air conditioning is hotter than the air around it is because it is made primarily of glass, glass allows sunlight to pass through freely, much of the light is absorbed by the seats and the dashboard and converts it into heat. Heat does not easily return through the glass, so it is trapped inside the car. A parked car will always end up much hotter than the air around it. The temperature of a car can increase between 10 and 20 degrees in just 10 minutes. This varies depending on the city and type of car, interior and exterior color, window tint, where it is parked, shade, direction of the car and time of day.

In 30 minutes, the interior temperature increases by an average of one degree per minute.

In 60 minutes, 43 degrees more than the outside temperature.

In 90 minutes, 48 ​​degrees higher, if the outside temperature is 90 degrees, this is equivalent to 138 degrees, higher than the highest outside temperature ever recorded on Earth.
