Which heat transfer doesn't require a medium?
Radiation is the heat transfer method that does not require a medium. It can occur through empty space, such as from the sun to the Earth, without the need for a material medium.
What is the difference between conduction and convection?
Conduction is the transfer of heat through direct contact between objects or substances. Convection, on the other hand, involves the transfer of heat through the movement of fluids (liquids or gases). In conduction, heat is transferred through a stationary medium, while in convection, the medium itself moves to transfer heat.
What does conduction and convection have in common?
Conduction and convection are both methods of heat transfer. They both require a material medium for the transfer to occur - conduction is through direct contact between materials, while convection involves the movement of fluids.
What is the flow of energy from a warmer to cooler material called?
The flow of energy from a warmer to cooler material is called heat transfer. This process occurs through conduction, convection, or radiation depending on the medium through which the energy is being transferred.
How do particles transfer through radiation?
Particles can transfer through radiation by a process called scattering, where they collide with atoms or molecules in the medium they are passing through. This interaction can cause the particles to change direction or lose energy as they move through the medium. In some cases, particles may also be absorbed by the material they are passing through.

What three ways can heat travel through substances?
Conduction - Process of heat transfer through a medium or material without any movement of the medium or material. Convection - transfer of heat from one place to another through the movement of fluids. A fluid with a given density rises within a fluid of greater density and sinks within in a fluid of smaller density. Radiation - transfer of heat, in the form of waves from one place to another without a medium.

By which mode of heat transfer heat is transferred in solids?
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..
How can there be gravity in space?
Quite simply, no material medium is required to transmit the force of gravity.
Where do mechanical waves not transfer energy?
Mechanical waves do not transfer energy in a vacuum because they require a medium, such as air, water, or a solid material, to propagate. In the absence of a medium, mechanical waves cannot transfer energy as they have no particles to oscillate and carry the energy.
What do conduction and convection use that radiation does not what does radiation use instead?
Conduction and convection require a medium (such as a solid or fluid) to transfer heat, whereas radiation can transfer heat through empty space without a medium. Radiation uses electromagnetic waves to transfer heat instead of relying on a material medium.
Does convection require medium?
yes
What is the only way to transfer heat in a vacuum?
The only way to transfer heat in a vacuum is through radiation. Heat transfer by convection and conduction require a medium, such as air or a solid, to transfer energy. In a vacuum, radiation is the only method by which heat can move.
