Physcial Science Please explain the difference between temperature and heat and their similarities if any. This definition merely allows one to place in order of temperature a number of objects. To assign numerical values, it is necessary to establish a scale of temperature.
Heat is defined as energy transferred as a direct result of temperature difference.
Hence, heat is seen as energy undergoing a particular process rather than as a particular 'form' of energy. Heat contributes, along with work, to changes in the internal energy of a system, though it is impossible to say how much of the internal energy was provided as heat and how much as work unless the entire history of the system is known. Heat may be transferred from place to place by conduction, convection or radiation. Heat is also used to refer, somewhat improperly, to the internal kinetic energy of a body arising from the random microscopic motion of the atoms and molecules that it contains.
