Radiation transfers energy by light waves (including visible light). Photons move through the medium and hit molecules (but the molecules stay in place).***
Conduction transfers energy between molecules, but the molecules stay in place. Since molecules stay in place, it often in times takes place in solids. In a more technical and simplify way: a molecule transfers its kinetic energy (vibrations) to other near by molecules. The original molecule looses kinetic energy, and the surrounding molecules gain energy, but the total energy is always conserved. If energy seems to be lost is most likely because of the air molecules which also surround the solid and could enter and escape the system. ***
Convection, in contrast to the other two, transfers its energy by moving its molecules (or even atoms in that matter) around the system. Convection takes place naturally in fluids (which include liquids and gases), and the whole purpose (in a physical-law point of view) is to bring balance to the system.
**************************************
Thermos apply these basis to minimize as muchenergytransfer as possible, meaning that it will keep your energy drink as cold as possible in a hot day, and at the same time it could keep your coffee drink as hot as possible in a cold day.
Radiation is reduced by having some sort of thick layer (like a metal as it is with aluminum alloy). The thicker (or denser) the better.
Because of the radiation that impacts the thick layer (relatively speaking), the layer will heat up, and the denser the material the faster it will heat up. And it so happens that most materials used are solids (like metal-alloys) and solids so happen to have the properties of conduction (because they are very dense). To minimize energy transfer for conduction, manufacturers use a second layer inside the first one, but contact between the two only happens at the top of the container (mostly in a form of circumference).
If between the two layers there's a fluid, convection will take place, and thus it won't be so good. Manufacturers then prefer to solve thisinconvenienceby eithercompletelyremoving the fluid (make a vacuum), or completely replacing it with an isolating-like material (like gel in case a vacuum is not possible), this way there would be little convection between the two layers.
What else can I help you with?
How was radiation fundamentally different from conduction and convection how is radiation fundamentally different from conduction and convection?
Radiation differs from conduction and convection in that it does not require a medium to transfer thermal energy. Conduction transfers heat through direct contact between materials, while convection involves transferring heat through the movement of a fluid. Radiation can occur in a vacuum and does not rely on the movement of particles.
Is thermal energy transferred through conduction convection or radiation?
Thermal energy can be transferred through conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between particles, convection involves the movement of a fluid to transfer heat, and radiation is the transfer of heat through electromagnetic waves.
What are the different method of heat transfer?
The three main methods of heat transfer are conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between materials. Convection involves the transfer of heat through the movement of fluids such as liquids or gases. Radiation is the transfer of heat through electromagnetic waves.
Are convection radiation and conduction all process of heat transfer?
Yes, convection, radiation, and conduction are all processes of heat transfer. Convection is the transfer of heat through fluid motion, radiation is the transfer of heat through electromagnetic waves, and conduction is the transfer of heat through direct contact between materials.
Could heat travel by conduction convection and radiation?
Yes, heat can travel through conduction, convection and radiation. Conduction is the transfer of heat through direct contact between materials, convection is the transfer of heat through the movement of fluids like air or water, and radiation is the transfer of heat through electromagnetic waves.

Why does the energy from the sun travel to Earth by radiation instead of by convection or conduction.?
Convection and conduction require matter to travel through, and there is no matter between Earth and the Sun

What are various methods of heat transfer?
The various methods of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between materials. Convection is the transfer of heat through the movement of fluids (liquids or gases). Radiation is the transfer of heat through electromagnetic waves.
How is transfer of energy by radiation differ from either conduction or convection?
Transfer of energy by radiation does not require a medium and can occur through a vacuum, unlike conduction and convection which require a material medium. Radiation involves the movement of electromagnetic waves, such as infrared radiation, while conduction and convection involve the transfer of heat through direct contact or movement of a fluid, respectively. Radiation is not dependent on the temperature difference between objects, unlike conduction and convection which rely on temperature differentials for heat transfer.
How is heat transferred between object or places?
One of three ways: conduction, convection, or radiation.
Why does the energy from the sun travel to Earth by radiation instead of by convection or conduction?
Energy from the sun travels to Earth by radiation because space is a vacuum and there is no medium for convection or conduction to occur. Radiation is the most efficient way for heat to transfer through the vacuum of space.
What are the differences between radiation, conduction, and convection in terms of heat transfer?
Radiation is the transfer of heat through electromagnetic waves, conduction is the transfer of heat through direct contact between objects, and convection is the transfer of heat through the movement of fluids or gases.
