• It could undergo a chemical reaction, exo or endo thermic. Heat is related to the Conservation of Energy. All of our ideas on energy still hold true, energy can be transformed from one type to another or transferred from one object to another. ΔKE + ΔGPE +Δ EPE + ΔWork + ΔQ (Heat) + ΔElec + ΔQ stays constant. •Thermodynamics, science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work. •Essential University Physics: Volume 1 (3rd Edition) answers to Chapter 16 - Section 16.3 - Heat Transfer - Got It? - Page 292 16.3 including work step by step written by community members like you.

You can feel heat transfer from a fire or the Sun. Yet the space between Earth and the Sun is largely empty, without any possibility of heat transfer by convection or conduction. Similarly, you can tell that an oven is hot without touching it or looking inside—it just warms you as you walk by. In these examples, heat is transferred by radiation.

Energy is a property of matter that can be converted into work, heat or radiation. Strictly speaking, both work and heat are processes by which energy can be changed but we don't need to worry about this subtlety here. A good analogy is that energy is like money in the bank, while heat, work and radiation are like cash, checks and money orders.
