Why Is Enthalpy Of Formation Of Oxygen Zero? The enthalpy of formation for an element in its elemental state will always be 0 because it takes no energy to form a naturally-occurring compound. … When a substance is formed from the most stable form of its elements, a change in enthalpy takes place. Why is
How Is The Internal Energy Change In Isothermal Process? The internal energy change for isothermal processes is known to be equal to zero. … But in the case of liquid vaporization (e.g. liquid water to steam) (boiling at constant temperature), the internal energy change is not zero. How does internal energy change during an isothermal
What Is Another Name Of Adiabatic Process? In compressor theory, the terms adiabatic (no heat transfer) and isentropic (constant entropy) are used interchangeably. This is quite valid for the context in which they are used. (The actual definition of an isentropic process What is the opposite of adiabatic process? In a sense, isothermal process can
