Conduction
Explanation:
If one touches a hot iron, the mode of heat transfer is conduction. Heat moves from a region of higher temperature to one at lower temperature until thermal equilibrium is established.
- There are three modes of heat transfer which are conduction, convection and radiation.
- Heat transfer by contact of one body with another is conduction. A hot body in contact with a cold one transfers heat by the vibration of particles of the medium.
- This is exemplified when a hot pot is touched.
