PV Work Another common type of work is pressure-volume work. This is work done by frictionless pistons andideal gases. The equation to calculate the expansion or compression of a gas is: w = -PΔV where w is work, P is pressure, and ΔV is the change in volume Sign Convention for ...
●Secondly, think carefully whether you really understand the meaning of a term or the use of an equation (方程式). A good way to test your understanding is to explain a concept to a classmate or someone else. ●Thirdly, pay attention to things which have something to do with chemistry in...
