As an expert in the field of environmental science, I specialize in understanding the dynamics of heat transfer and the effects of solar radiation on various environments, including the interior of a car. The rate at which the temperature rises inside a car is a complex phenomenon influenced by several factors, including the external temperature, the duration of exposure to sunlight, the color and material of the car's exterior, and the car's design.

When a car is parked in direct sunlight, the windows and the metal exterior act as a greenhouse, trapping heat inside. The sun's rays pass through the glass windows and are absorbed by the car's interior surfaces, which then re-radiate the heat back into the air. This process is known as the greenhouse effect. The rate of temperature increase can be quite rapid, especially on a sunny day.

The initial temperature inside the car is typically close to the ambient outdoor temperature. However, as time passes, the temperature inside the car can rise significantly higher than the outside temperature. The rate of increase is not linear and will depend on the aforementioned factors.

According to the information provided, on a sunny day with an outdoor temperature of 70 degrees Fahrenheit, the temperature inside the car can reach 104 degrees after half an hour and 113 degrees after an hour. This is a substantial increase and highlights the rapid rate of temperature rise in a short period.

Furthermore, when outdoor temperatures range from 80 to 100 degrees Fahrenheit, the interior temperature of a car parked in direct sunlight can quickly climb to between 130 to 172 degrees Fahrenheit. This extreme temperature rise can occur within a matter of hours and can pose serious risks to anyone or anything left inside the vehicle.

It's important to note that darker colors absorb more heat than lighter colors, so cars with darker exteriors will heat up faster than those with lighter colors. Additionally, the design of the car, including the size of the windows and the amount of glass, can also affect how quickly the interior heats up.

To mitigate the rapid temperature rise, it's advisable to park in shaded areas when possible, use sunshades for the windows, and avoid leaving pets or children in the car, as they are particularly vulnerable to the dangers of heatstroke.

In conclusion, the rate at which the temperature rises inside a car exposed to sunlight is influenced by a variety of factors and can lead to a significant increase in temperature within a short period. It's crucial to be aware of these dynamics to ensure the safety and comfort of all occupants.
