WebJan 30, 2024 · Thus, in the equation ΔU=q+w w=0 and ΔU=q. The internal energy is equal to the heat of the system. The surrounding heat increases, so the heat of the system decreases because heat is not created nor destroyed. Therefore, heat is taken away from the system making it exothermic and negative. WebJan 24, 2024 · The internal energy of ideal gases is a function of temperature only. Hence, in isothermal processes, as the temperature remains constant, there is no change in the internal energy of an ideal gas, i.e., \ (\rm {∆U = 0}\). This is because the intermolecular forces of attraction in the molecules of an ideal gas are negligible.
