Understanding the science behind how cars heat up can help you take more effective measures to mitigate the risks. Several scientific principles contribute to the rapid increase in temperature inside a vehicle.
7.1. Greenhouse Effect
The greenhouse effect is a primary factor in how cars heat up. Sunlight enters the car through the windows, and much of this energy is absorbed by the interior surfaces, such as the seats, dashboard, and floor. These surfaces then re-emit the energy as infrared radiation (heat). Unlike sunlight, infrared radiation cannot easily pass through the glass windows, so it becomes trapped inside the car, causing the temperature to rise.
7.2. Conduction and Convection
Conduction and convection also play roles in heating the air inside a car. Hot surfaces, such as the dashboard and steering wheel, heat the air directly through conduction. As the air near these surfaces heats up, it becomes less dense and rises, creating convection currents that distribute the heat throughout the car’s interior.
7.3. Radiation
Radiation is another way heat is transferred inside a car. Hot objects emit thermal radiation, which can be absorbed by other surfaces, causing them to heat up as well. This process contributes to the overall increase in temperature inside the vehicle.
7.4. Impact of Dark Colors
Dark-colored cars absorb more sunlight than light-colored cars, leading to a greater buildup of heat inside the vehicle. Dark surfaces absorb more energy from the sun, which then gets trapped inside the car.
