Re: JNU MSc Physics Entrance Question Paper
Below I am providing you some questions of from question paper of JNU MSc Physics Entrance Exam and attaching a PDF attachment which has detail information regarding this that you can down load for free: Q1. A train of mass M is traveling with uniform velocity on a level line. The last carriage, whose mass is m, becomes uncoupled at an instant. The driver discovers it after traveling a distance l and stops the engine. The resistance to the motion is uniform and proportional to the weight. The pull of the engine is uniform. When both parts of the train come to rest, the distance between them is Q2. Let T P, , be the set of standard thermodynamic variables respectively denoting the chemical potential, pressure and temperature of a fluid. If s and v be respectively the entropy and volume per particle and , / 1 n v then identify the correct thermodynamic relation. Q3. The equation of state of an ideal gas is , BT nk p where p is the thermodynamic pressure and V N / n is the thermodynamic variable for the number of particles per unit volume. The n dependence of the free energy f per unit volume of the ideal gas is obtained by the following expression, where T c is temperature-dependent constant Q4. Identify the correct statement. (a) The entropy of a system always increases when it undergoes an irreversible process (b) The entropy of a system always decreases when it undergoes an irreversible process (c) The second law of thermodynamics follows directly from principle of conservation of energy (d) The internal energy of an ideal gas depends on its temperature JNU MSc Physics Entrance Question Paper |
