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.
Find amplitude of electric field ina parallel beam of light of intensity 2W/m2 Ans: Given that intensity I=power/area=2W/M2 by using this formula :intensity I=(Emax^2/2c mue not
Show the mathematical relation connecting n,u,v and R for refraction at a spherical surface concave towards a point object in a denser medium producing a virtual image.
Can the batteries used in the torch lights be recharged after their discharge? Give reason? Ans) No,because the NH4Cl corrods the zn containger gradually.so with out anode redox
