Conduction:
Conduction is the process of heat transfer through a material or substance without any movement of the substance itself. It occurs when two objects are in contact with each other and there is a temperature difference between them. Heat flows from the hotter object to the cooler one until they reach thermal equilibrium.
Convection:
Convection is the process of heat transfer through the movement of fluids such as liquids or gases. It occurs when a fluid is heated and its density decreases causing it to rise, and cooler fluid to take its place. This creates a continuous flow of fluid that transfers heat from one location to another.
Radiation:
Radiation is the process of heat transfer through electromagnetic waves. Unlike conduction and convection, radiation does not require a medium to travel through. When an object is heated, it emits heat in the form of electromagnetic waves which can be absorbed by other objects and cause them to heat up.
Ionization:
Ionization is the process of converting an atom or molecule into an ion by adding or removing electrons. While this process can release heat, it is not a method of heat transfer.
