Heat transfer occurs in three primary ways: conduction, convection, and radiation.

Conduction refers to the transfer of heat through direct contact between materials. This process occurs on a molecular level, where the kinetic energy of molecules is passed from one to another. For example, when a metal spoon is placed in a hot pot of soup, heat from the soup is conducted through the spoon and can be felt at the handle.

Convection involves the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. As a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks. This creates a current that distributes heat throughout the fluid, such as in a pot of boiling water where hot water rises and cooler water sinks.

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur even through a vacuum. This means that heat can be transferred through empty space without the need for a medium. An example of radiation is the warmth felt from the sun, as the heat travels through the vacuum of space to reach us.

The other options mention terms like compression and integration, which do not define methods of heat transfer. Understanding these three established methods is crucial for anyone
