Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
Identify instances of the first law of thermodynamics working in everyday situations, including biological metabolism. Calculate changes in the internal energy of a system, after accounting for heat transfer and work done.
16 sie 2021 · The first law of thermodynamics is given as \(\Delta U = Q - W\), where \(\Delta U\) is the change in internal energy of a system, \(Q\) is the net heat transfer (the sum of all heat transfer into and out of the system), and \(W\) is the net work done (the sum of all work done on or by the system).
