Is a Vacuum a Good Insulator: The Science Behind Vacuum Insulation and Its Benefits
No, a vacuum is not a good insulator. While it does not contain air, which is a good conductor of heat, vacuum itself is not a thermal insulator. Without any physical contact or substance to transfer heat, thermal energy can still travel through infrared radiation, which means that vacuum is not a complete insulator. However, creating a vacuum is often used to reduce heat transfer in some applications such as thermos bottles and space technology.
