Thermodynamics and energy
1 Answer

Thermodynamics and energy:

Definition: Thermodynamics can be defined as the science of energy fundamental subject which describes basic laws governing the occurrence of physical process associated with transfer of energy/ conversion. Also establishes the relationship between the physical properties affected by these processes. therm (heat) + dynamics( power)

  • why to study thermodynamics? thermodynamics tells us whether process is feasible or not? and if it is then in which direction? For all natural processes involving energy transfer/ conversion, there re certain directional constraints, quantitative constraints. this subject guides this principle.

The laws of thermodynamics govern the principles of energy conversion. These laws have been formulated from common experiences. The law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. Example: A rock falling off a cliff, Human diet

Application areas of thermodynamics: 1) Heart (human) 2) Household utensils and appliances. heating & Ac, refrigerator, pressure cooker, water heater, shower iron, computer & TV. 3) Automotive engine, rockets, jet engines, conventional or nuclear power plants, solar collectors, etc 4) Size, location, and power input of the fan of computer is also selected after an analysis that involves thermodynamics.
