Thermodynamic laws:
First law of thermodynamics
In internal energy of a system the change is the total heat transferred to or from the system & the work done on or by the system.
Second law of thermodynamics
The entropy is a measure of the unavailability of a system's energy to do useful work of a closed system tends to enhance with time.
Third law of thermodynamics
For changes including only perfect crystalline solids at absolute zero, the change in the over all entropy is zero.
The energy to which the human ears are sensitive is named as sound. In general all parts of waves are produced in an elastic material phase, Irrespective of while these are listen
Q. Give the applications of Moseley's law. (i) The elements are organized in the periodic table according to the atomic numbers and not according to the atomic weights. (ii
The current is an RL circuit drops from 1.1 A to 13 mA in the first second following removal of the battery from the circuit. If L is 12H, find the resistance R in the circuit.
Polygon of force This topic just builds on the previous Triangle of Forces. Consider three forces A, B and C. A and B can be added by drawing a triangle to give a re
A particle of mass , initially moving with a speed v, collides head on ELASTICALLY with an identical particle initially at rest. a. Do you expect the total mass of the particles
A thermal imager is used to measure the temperature of a target surface (ε = 1) in the test section of a wind tunnel. The thermal imager must view the target though a window. The t
Friction of rough surfaces Place two pieces of sandpaper together. Notice the friction that is formed when one is rubbed against the other. Now put some grease among the pieces
An element exists in two solid phases (labelled P1 and P2). The standard molar entropies of P1 and P2 are 21.9 J mol -1 K -1 and 23.3 J mol -1 K -1 respectively. The
