Heat energy refers to the form of energy that is transferred between systems or objects with different temperatures, moving from the warmer object to the cooler one. It is a manifestation of the kinetic energy of molecules, atoms, or particles within a substance. As particles in an object move more rapidly, they collide with each other, and this movement is perceived as heat. Heat energy plays a critical role in a variety of physical processes, such as cooking, weather patterns, and mechanical work. It is often measured in joules or calories and can be transferred by conduction, convection, or radiation.
