NEETPhysicsThermal Properties of Matter
Match the following. ( array |c|l|c|l| & Column-I & & Column-II (A) & e = ₀^ e_ , d & (a) & T^a (B) & _m T = b & (p) & Wien's displacement law (C) & a₂ & (n) & Unity for black body (D) & e a for black body & (s) & Absorptive power array )
Options
- Aa-p b-r c-s d-q
- Ba-p b-s c-r d-q
- Ca-q b-r c-s d-p
- Da-q b-p c-s d-r
Correct answer
D. a-q b-p c-s d-r
Step-by-step solution
Rate of heat emitted is given by emissivity ( ) (Temperature) ( ^4 ) Where sigma is stephan boltzmann constant. Wavelength ( ) Temperature= constant it is given by wien's displacement law. ' a ' is given as absorptive power of the material. By Kirrchoff's law, absorptive power = emissivity power (a=e)
