Heat is known to be a very special form of energy. Unlike others forms of energy, heat has limited uses. Explain the main different features of heat that makes it special from the other forms of energy (1 mark). Given an example of the special features of heat that limits the efficiency of the use of heat in energy transfer (1 mark). Explain what quantity of physics and what law of physics encapsulates this feature of heat responsible for its limited use (1 mark)
