What is the temperature inside a car trunk when the outdoor temperature is 30 degrees?

When the outdoor temperature is 30 degrees, the temperature inside a car trunk can exceed 60 degrees. Below are specific details about in-car temperatures: 1. Comfortable temperature range: The ideal temperature inside a car is between 20 to 27 degrees Celsius. Temperatures above 28 degrees Celsius can make people feel uncomfortably hot, while temperatures below 14 degrees Celsius can make people feel cold. 2. Air circulation mode: It's necessary to regularly switch between internal and external air circulation modes in a car. If the car remains in internal circulation mode for an extended period, the oxygen level inside the car will gradually decrease, and carbon monoxide produced by the engine may accumulate, which can lead to poisoning. Regularly switching to external circulation mode can bring fresh air into the car.
As someone who drives year-round in hot climates, I'm very familiar with the issue of summer trunk temperatures. When it's 30°C outside, a car trunk parked in the sun for several hours can reach between 40 to 60°C, depending on specific conditions. I once measured a trunk temperature of 55°C when parked in an uncovered parking lot - over 20°C hotter than outside. This happens because the trunk is an enclosed space where body materials like metal and glass absorb heat, combined with poor air circulation that traps hot air. Parking location is crucial - parking in shade or garages can reduce temperatures to 35-45°C. Avoid storing perishable food or electronics as they can get damaged. Regularly cleaning out clutter helps with heat dissipation, but generally try to avoid storing sensitive items for extended periods during hot weather.
I have some interest in thermodynamics, so I'm happy to explain this issue. When the outdoor temperature is 30 degrees, the temperature inside a car's trunk can be significantly higher, typically ranging between 45 to 60 degrees. Solar radiation is absorbed through the windows or car body, and the heat gets trapped in the enclosed space without effective dissipation, leading to internal temperature rise. Weather factors like wind speed and humidity also play a role, but overall, parking duration is the key factor. I've read some data indicating that temperatures can surge by 15 to 30 degrees within just a few hours. To protect items, it's advisable to park in shaded areas or use sunshades, which can slow down the rate of temperature increase.
