The relationship between high temperature of air compressor and air compressor

The degree to which an object is hot or cold is called temperature (heat). We know from the law of conservation of energy that work and heat can be mutually converted, and the increase in temperature everywhere in the compressor is converted from mechanical friction work and compression work.
