How does the first law of thermodynamics apply to air compressors?

Answer 1

The first law of thermodynamics, which states that energy cannot be created or destroyed, only transformed, applies to air compressors in that they convert electrical energy into mechanical energy to compress air. During this process, the work done on the air increases its internal energy, resulting in a rise in temperature and pressure. Additionally, some energy is lost as heat due to inefficiencies, illustrating the conservation of energy principle. Thus, air compressors exemplify the transformation and conservation of energy in practical applications.
