Wouldn’t it be the opposite? Because with nothing to impede the heat dissipation, wouldn’t it dissipate faster instead of slower?
In: Physics
Heat can be transferred in 3 ways: conduction (solid – to – solid contact), convection (circulation of air or liquid), and radiation.
Radiation is less effective than the other two methods for transferring heat. In using a vacuum thermos or by putting a vacuum between a hot object and a cold environment, the only way for the heat to escape is radiation.
