Transfer Of Thermal Energy

Thermal energy always flows from a region of higher concentration to a region of lower temperature. Conduction: Conduction is the process of thermal energy transfer without any flow of the material medium Conduction occurs mostly from solid to solid due to molecular vibration. The particles at A absorbs heat energy …
