12.2 First law of Thermodynamics: Thermal Energy and Work

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.

What is the difference between enthalpy (H) and heat (q)?

WebEnthalpy (H) has to do with thermodynamics; it is a state function, at constant pressure, used in chemical and biological systems. This means that enthalpy depends only on the final energy, pressure, and volume and not the path the system took to get to the final state. This is the change in internal energy that is equal to the heat transfer ... WebStrictly, H = U + PV where U = internal energy, P =Pressure, and V = Volume. Enthalpy is an extensive property of substances (i.e. it depends on the amount of substance, as do mass and volume). It is a state function i.e. the value of any enthalpy change does not depend on how any change was made, but only on the initial and final state of the ...
