Radiation is the type of heat transfer that occurs in the form of waves. This transfer of heat can occur through empty space and does not require a medium. Examples include sunlight and heat transfer from a fire.
Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.
Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).
The form of energy transfer that occurs when heat is transferred from one object to another is called conduction.
Heat transfer in liquids and gases occurs primarily through convection, which is the transfer of heat through the bulk movement of the fluid. In convection, the hotter fluid rises and the cooler fluid sinks, creating a circulation pattern that transfers heat. Conduction, the transfer of heat through direct contact between molecules, also occurs in liquids and gases but is less efficient compared to convection.

Heat transfer occurs when a kettle is placed on a lit gas ring, and the water is brought to the boil.
Radiation is a heat transfer that can occur in a vacuum because it does not rely on the presence of a medium to propagate. It is the transfer of heat through electromagnetic waves, such as infrared radiation.
No. When two bodies or regions are at the same temperature, equilibrium is already reached & no transfer of heat occurs.
