... T)-diagram with isotherms at T 1 =2andT 2 =1.5(arbi- trary units) and adiabatics T · V 5/3 =1.5 and 0.5, as for an ideal gas. Further expla- nation is given in the text We shall now calculate ... thermodynamics. On the other hand, as we shall see later, a cyclically operating (or reciprocating) real heat pump is perfectly feasible, where an amount of heat Q 2 is absorbed at a low temperat...

... was in fact mainly casting doubt on the idea that a system could be in a state of coherent quantum mechanical super- position with nontrivial probabilities of states that are classically mutually 17 Relativistic ... with a question, which we paraphrase as follows: “What is the ‘state’ of an unobserved cat confined in a box, which contains a device that with a certain probability ki...

... we shall return to later. In this equation v = V N , and a and b are positive constants. For a = b = 0 the equation reverts to the ideal gas law. A T,p-diagram for H 2 O (with T as abscissa and ... temperature scales, such as, for example, Fahrenheit and R´eaumur, are not normally used in physics. As we shall see, the Kelvin temperature T plays a particular role. In the ideal gas equa...
