An irreversible process can go in one direction but not the reverse, under a given set of conditions. For example, although body fat can be converted to do work and produce heat transfer, work done o ...

... The process in which the system after passing through various stages ( pressure, volume and temperature changes) returns to its initial condition is called a cyclic process. i) In cyclic process, dU = 0. Hence dQ = dW ii) P – V graph for a cyclic process is a closed curve. In cyclic process total he ...

The First Law of Thermodynamics
... the MKS system, R = 8.314 J/mole-K. If pressure is given in atmospheres and volume in liters, then R = 0.08206 L-atm/mol-K. From these two expressions for R, it should be obvious that a “liter-atmosphere” has dimensions of energy (or work). Kinetic Theory of Ideal Gases The microscopic physics expla ...
