Respuesta :
In this type of system, there will be energy transfer but no mass transfer, such type of system is called a closed system.
In this system air (refrigerant) is compressed by a pump which means work input is given so that it leads to an increase in pressure/temperature.
Energy, in physics the ability to do work. It can exist in electrical, kinetic, thermal, electrical, chemical, nuclear, or various other forms. In addition, there is heat and work.
