![]() ![]() ![]() Heat transfer is from the outside air, even at a temperature below freezing, to the indoor space. ![]() The great advantage of using a heat pump to keep your home warm, rather than just burning fuel, is that a heat pump supplies \(Q_h = Q_c W\). There is heat transfer \(Q_c\) into the system from a cold reservoir along path DC, and heat transfer \(Q_h\) out of the system into a hot reservoir along path BA. Heat was not formally recognized as a form of energy until about 1798, when Count. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work. The volume remains constant but temperature and pressure change according to the process. A typical example of an isochoric process is addition or removal of heat from a closed system. Thus for an isochoric process the work done is always zero. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. Thermodynamic work done in an isochoric process is given by,, since volume is held constant. The area inside the loop is negative, meaning there is a net work input. thermodynamics, science of the relationship between heat, work, temperature, and energy. ![]()
