What else can I help you with?
Does conduction require direct contact between objects objects have to be touching?
Yes, conduction does require direct contact between objects for heat transfer to occur. This is because heat is transferred through the collision of particles in direct contact with each other. If there is no direct contact, conduction cannot take place.
Why can heat travel through space by radiation but not by conduction or convection?
Heat travels through space by radiation because electromagnetic waves can propagate in a vacuum. In contrast, conduction and convection require a medium like a solid, liquid, or gas to transfer heat through collisions or circulation of particles. Since there is no medium in space, conduction and convection cannot occur.
Does Heat require a medium?
No, heat does not require a medium to travel. Heat can be transferred through conduction, convection, or radiation, and can travel through a vacuum as well.
What do conduction and convection use that radiation does not?
Conduction and convection require a medium (such as a solid or fluid) to transfer heat, while radiation does not need a medium and can transfer heat through electromagnetic waves.
What do conduction and convection use that radiation does not?
Conduction and convection use matter (such as solids, liquids, or gases) to transfer heat, while radiation does not require matter and can transfer heat through electromagnetic waves.
Does conduction require a medum?
Yes, since there would be no conduction of sound in a vacuum.
Does conduction require medium?
Only for trains and orchestras.
Does radiation require movement of matter?
no it doesn't, only conduction and convection

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 is borderline AV conduction Delay?
Borderline atrioventricular (AV) conduction delay refers to a slight prolongation in the time it takes for the electrical signal to travel from the atria to the ventricles of the heart. While it may not meet the criteria for a definitive diagnosis of AV conduction delay, it can be an indicator of potential heart conduction issues that may require monitoring.
Why is conduction not responsible for bringing heat to earth?
Conduction is the transfer of heat through direct contact. In the case of the Earth, there is no medium for heat to travel through via conduction since space is a vacuum. Instead, heat from the Sun reaches Earth through radiation, which does not require a medium.
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.
