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),
National Energy Research Scientific Computing Center National Energy Research Scientific Computing Center The National Energy Research Scientific Computing Center, or NERSC, is a high performance computing (supercomputer) user facility operated by Lawrence Berkeley National Laboratory for the United States Department of Energy Office of Science. As the mission computing center for the Office of Science, NERSC houses high performance computing and data systems used by 7,000 scientists at national laboratories and universities around the country. NERSC's newest and largest supercomputer is Cori, which was ranked 5th on the TOP500 list of world's fastest supercomputers in November 2016. NERSC is located on the main Berkeley Lab campus
