P 6 - 26 The isothermal compressibility of water is 50 x 10-6 atm-1 and c P = 4.18 x 10 3 J kg-1 K-1. Other properties of water are given in the previous problem. Calculate the work done as the pressure on 1 g of water in a hydraulic press is increased reversibly from 1 atm to 10,000 atm (a) isothermally, (b) adiabatically, (c) Calculate the heat evolved in (a) the isothermal process.
Entropy . 1. has the same value irrespective of path as long as path is reversible 2. is an exact differential of some function which is identical as entropy 3. 4. for reversible process only Calculation of Entropy change . 1. Entropy is a state function. The entropy change is determined by its initial and final states only
There are four thermodynamic processes, namely Isothermal, isochoric, isobaric and adiabatic processes. Isothermal Process (constant temperature) In an isothermal process, system temperature is kept constant. Theoretically, the analyzed system is an ideal gas. Ideal gas temperature is directly proportional to ideal internal gas energy (U = 3/2 n R T). T does not change, so […]
Answer. Essential conditions for an isothermal process. (i) The process of compression of expansion should be infinitely slow. So as to provide a sufficient time for the exchange of heat. (ii) The walls of the container must be perfectly conducting to allow free exchange of heat between container and surroundings. Consider a cylinder with μ ...

1. The heat capacity is a property that defines how much energy is saved in a material for a given change of temperature. A definition of it will -- out of necessity -- always contain a (possibly virtual) change of temperature. In the equation of state one other variable will have to be allowed to change to keep the equation of state satisfied.
