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.
Convection is the type of heat transfer that occurs only in fluids. It involves the movement of fluid particles carrying heat energy from one place to another, resulting in the transfer of heat.
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 you place a hot pot on a cold surface, with heat transferring from the pot to the surface until they reach thermal equilibrium.

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.
Heat transfer occurs whenever two or more objects of different temperatures are in contact with each other. Spilling hot water on yourself causes heat transfer from the water to you. When you drive your car the hot engine and radiator transfer heat to the surrounding air in order to cool the engine.
