Which of the following methods is not a way of transferring heat energy?

Sublimation is the process where a substance transitions from a solid state to a gaseous state without passing through the liquid state, such as dry ice turning into carbon dioxide gas. While sublimation involves energy transfer, it does not function as a method of transferring heat in the same way that radiation, convection, and induction do.

Radiation is the transfer of heat in the form of electromagnetic waves, allowing heat to be transferred through a vacuum (like sunlight warming the Earth). Convection involves the movement of fluid (liquid or gas) where warmer areas of the fluid rise and cooler areas sink, creating a current that transfers heat. Induction, particularly in heating applications, involves the transfer of heat through magnetic fields to heat conductive materials, like in induction cooktops.

In contrast, sublimation primarily describes a phase change of a material rather than a method of heat transfer. Understanding the different mechanisms of heat transfer is crucial in power engineering, where controlling temperature and energy efficiency is vital for system performance.
