There are three ways to transfer heat:1. Conduction
2. Convection
3. Radiation
Only the third way works in the case of a vacuum. In this third way, the radiation in question is electromagnetic waves - usually infrared (it depends on the temperature of the object). Just like light - which is also an electromagnetic radiation - other electromagnetic waves travel especially well through empty space.
Exactly the same way as light from the sun and radio signals from the Mars rovers travel through the vacuum of space.
heat or light radiation can travel through a 100% vacuum
Heat energy is transferred by conduction, convection and radiation. In a vacuum, heat energy can only be transferred by radiation.
Only by radiation. Infrared waves waves don't require a material medium to pass through. Heat energy is transmitted even through vacuum in the form of infrared waves. We get heat energy from sun in this way.
Because radiation is the only method that works in the vacuum of space.
A vacuum motor can generate heat, which is transferred through radiating patterns, mostly.answer 2 heat can transfer by conduction, radiation, and convection (a special case of conduction).Heat can travel through a vacuum by radiation. I hope the sun felt warm at your place today.

Transfer of heat energy through energy waves is called radiation.
Heat is transferred through contact between molecules.
Heat is transferred through contact between molecules.
The sun transfer heat through radiationAnswer'Heat' is not transferred. Rather, 'heat' describes the process of transferring energy. So, your question should read, 'How does the sun transfer energy to earth?", and the answer is by radiation.
a vacuum flask is not 100% vacuum. it contains some particles or gas molecules which absorbs a small amount of heat.
Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.
Heat is transferred through contact between molecules.
