WebWhat is Q heat physics? The symbol Q for the total amount of energy transferred as heat was used by Rudolf Clausius in 1850: “Let the amount of heat which must be imparted during the transition of the gas in a definite manner from any given state to another, in which its volume is v and its temperature t, be called Q” WebHeat ( Q) and work ( W) are the two ways to add or remove energy from a system. The processes are very different. Heat is driven by temperature differences, while work involves a force exerted through a distance. Nevertheless, heat and work can produce identical results. For example, both can cause a temperature increase.
