Explain
a.Stefan's law
b.Weans displacement law
c.Quasi static pressure
d.Law of conduction
Answers
a. Stephen's law:Stefan Boltzman law statement that the total Radiant heat energy emitted from a surface is proportional to to the fourth power of its absolute temperature.the law applied only to blackbodies,theoretical surface that absorb all incident heat radiation.
b. waens is the relationship between wavelength of maximum intensity a black body emits and it's temperature.
c. meaning of reversibility and quasi static processes.........a process is quasistatic if a process is infinetly slowly.now if a process is reversible,this means that we are always in equilibrium and this can only be the case if we do this very slowly thus any reversible process is quasi static.
d. thermal conduction is the transfer of heat buy microscopic collision of particles and movement of electrons within an organ.the microscopically colliding particles,the include the molecules,atoms and electrons,transfer Disorgsnized microscopic kinetic,potential energy jointly known as internal energy.
