Work (thermodynamics) of the energy went out as heat, and how much as work. This can be summarized by saying that heat and work are not state functions of the system. This is in contrast to classical mechanics, where net work exerted by a particle is a state function. Pressure–volume work (or "PV" work) occurs when the volume of a system changes. "PV" work is often measured in units of litre-atmospheres where = . However, the litre-atmosphere is not a recognised unit in the SI system of units, which measures P in Pascal (Pa), V in m, and PV in Joule (J),
Modern Woman: The Lost Sex Modern Woman: The Lost Sex Modern Woman: The Lost Sex is a 1947 work of scientific literature written by Ferdinand Lundberg and Marynia F. Farnham, M.D. which discusses the sociological and psychological context of American women in the post World War II era.
