What are the differences between heat and infrared radiation?

Heat and infrared radiation are both forms of energy transfer, but they differ in how they are produced and how they travel. Heat is the transfer of thermal energy between objects due to a temperature difference, while infrared radiation is a type of electromagnetic radiation that is emitted by all objects with a temperature above absolute zero. Infrared radiation is a specific type of heat transfer that occurs through electromagnetic waves, while heat transfer can occur through conduction, convection, or radiation.
