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.
Derive the mathematical expression PV r = constant for an ideal gas undergoing adiabatic reversible expansion.
i have to make a written project on this topic please tell me something what should i make
Electrons and holes in semi-counductor Metals have free electrons available in conduction band for conduction of electric current. As the valence band overlaps the conduction b
Loschmidt constant; Loschmidt number; NL: The number of particles per unit volume of an ideal gas at standard temperature & pressure. It has the value 2.687 19 x 10 25 m -3 .
The internal energy change when a system goes from state A to B is 40 kJ/mole. If the system goes from A to B by a reversible path and returns to state A by an irreversible path wh
The angular displacement of a body is a function of time and giving by equation h=10+3t+6t square,where t is in seconds.determine the angular velocity, acceleration when t=5seconds
