How is energy transferred calculated

WebFigure 1.9 (a) Here, the soft drink has a higher temperature than the ice, so they are not in thermal equilibrium. (b) When the soft drink and ice are allowed to interact, heat is transferred from the drink to the ice due to the difference in temperatures until they reach the same temperature, T ′ T ′, achieving equilibrium.In fact, since the soft drink and ice … WebThe first law of thermodynamics states that the change in internal energy of a closed system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is Δ U = Q − W. 12.6 Here, Δ U is the change in internal energy, U, of the system.
