Answer:
How does heat transfer between hot and cold objects by conduction?
Conduction happens when materials or objects are in direct contact with each other. The molecules in the warmer object vibrate faster than the ones in the cooler object. The faster vibrating molecules collide with the slower molecules. This makes the cooler molecules vibrate more quickly, and the object gets warmer
How does heat transfer from hot to cold or cold to hot?
Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body warming up.
What is the process of transfer of heat from a hot body to a cold body without any medium called?
The fastest method of heat transfer from hot body to cold body is radiation. Radiation occurs at the speed of light and doesn't require any medium for travelling. It takes place in form of electromagnetic waves.
