WebNov 17, 2024 · The third type of heat transfer— radiation —is critical to life on Earth and is important for heating bodies of water. With radiation, a heat source does not have to touch the object being heated; radiation can transfer heat even through the vacuum of space. WebI would say the first point to stress here is that heat by definition is the transfer of energy. 'Heat loss' can occur via convection, conduction or radiation. Clearly, the first two can be essentially reduced to zero by surrounding your coffee (or whatever) with a perfect vacuum. Creating a perfect vacuum is pretty much impossible though.
