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.
Let's say I have a pinball (solid sphere) with a given mass and radius, and it is held back at a certain distance from equilibrium on a spring. The spring constant k is given, and
(1) Holes works as virtual charge, although there is no charge on holes. (2) Effectual volume of hole is more than electron. (3) Mobility of hole is fewer than electron.

what are isotopes?
An object starts from point A and moves with constant acceleration in a straight line. 5 seconds after the start, it crosses point B, and 7 seconds after the start it crosses poin
A mild steel ring has a radius of 50mm and a cross-sectional area of 400mm 2 . A current of 0.5 A flows in a coil wound uniformly around the ring and the flux formed is 0.1mWb
what type of transformer we use in this
Q. Determine the elapsed time in kinematics? Let S = 1 + c 2 + c 4 + ........ Then, S = 1 + c 2 (1 + c 2 + c 4 +.......... ) S = 1 + c 2 S so, S - c 2 S = 1
The process of changing of a heavy nucleus into two lighter nuclei of comparable masses (after bombardment with a energetic particle) with liberation of energy is known as nuclear
#how entropy tells which process is spontaneous and which is non spontaneous.i also wana know that although 2nd law of thermodynamic is for heat engine and heat pump how it is rela
