Depends on the material itself(for conduction) or it's surface and the temperature(for radiation) - at very high temperatures(like a lightbulb filament), radiation is far more significant then conduction, but a heatsink in a normal PC is doing to be far more dependant on conduction then radiation...
What else can I help you with?
When conduction occurs between two objects do the two objects need to be touching?
No, conduction can occur between objects without them needing to be in direct contact. Heat conduction can happen through a material medium or in the form of radiation, where energy is transferred through electromagnetic waves.
Where does conduction convection and radiation happen in a house?
Conduction occurs through direct contact between objects like the floor and your feet. Convection happens when warm air rises and creates air currents like in a room with a heater. Radiation occurs when heat moves in waves through space, like sunlight coming through a window.
What type of energy transfer occurs through the flow of materials?
Heat transfer occurs through the flow of materials. When materials with different temperatures come into contact, heat will transfer from the hotter material to the cooler one until they reach thermal equilibrium. This can happen through conduction, convection, or radiation.
What direction does heat transfer go?
Heat transfer goes from an area of higher temperature to an area of lower temperature. This transfer can happen through conduction, convection, or radiation, depending on the medium through which heat is being transferred.
Why can't a condution occur in a space?
Conduction requires particles to physically touch to transfer heat. In a vacuum (like outer space), there aren't enough particles for conduction to happen efficiently. Heat transfer in space primarily occurs through radiation, where electromagnetic waves carry heat energy.

Is convection a chemical reaction?
no it is a type of conduction that can happen in liquids and gases, conduction happens in solids, and radiation happens in gases

How thermal energy transfers?
It can be transferred in three ways: Conduction, convection, and radiation. Conduction is transfer through a substance by contact between atoms. Convection is transfer in a gas (air) by causing air currents due to density effects. Convection can also happen in fluids like water. Radiation is by electromagnetic waves at the infra-red frequencies.

Conduction requires particles to physically touch to transfer heat. In a vacuum (like outer space), there aren't enough particles for conduction to happen efficiently. Heat transfer in space primarily occurs through radiation, where electromagnetic waves carry heat energy.
At what spead does transfer of heat take place?
Heat transfer is in three modes. Conduction, convection and radiation. In case of conduction, the speed of transfer depends on the conduction property of the material. In case of convection, the speed of transfer depends on the density of the liquid. In case of radiation, the speed of transfer of heat is at the speed of light in air medium and a little bit less in other denser medium.
What are the three different ways that thermal energy is transferred?
the process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods. Heat transfer flows from a body with high energy (higher temperature) to lower energy (lower temperature).
How is heat lost in a house?
Heat is lost in a house through conduction (transfer through materials like walls and windows), convection (transfer through air currents), and radiation (transfer through electromagnetic waves). This can happen when there are poor insulation, gaps in windows or doors, and inefficient heating systems. Proper insulation, sealing drafts, and using energy-efficient windows and doors can help reduce heat loss.
If you stand ten feet away from a large campfire heat is transferred to your skin how does this happen?
Heat is transferred through a combination of radiation, convection, and conduction. In this case, the campfire emits thermal radiation that travels through the air and is absorbed by your skin. The closer you are to the fire, the more heat you will feel due to the increased intensity of the radiation.
Why cant energy travel by conduction through empty space?
Conduction requires the presence of matter. The way conduction works, one atom or molecule bumps into another one, transferring heat energy.
