No answer description available for this question.
A. absolute temperature (T)
B. I2
C. f
D. t
E. 1/r
A. p = 0, x = 0 and a = 1
B. p=l,x = 0anda = 0
C. p = 0, x = 1 and a = 0
D. x – 0, a + p = 1
E. a=0,x + p= 1.
where a = absorptivity, p = reflectivity, X = transmissivity
A. p = 0, x = 0 and a = 1
B. p=l,T = 0anda = 0
C. p = 0, x = 1 and a = 0
D. x = 0, a + p = 1
E. a = 0, x + p = 1.
where a = absorptivity, p = reflectivity, x = transmissivity
A. Krichoff’s law
B. Stefan’s law
C. Wien’ law
D. Planck’s law
E. Black body law
A. less than those for gases
B. jess than those for liquids
C. more than those for liquids and gases
D. more or less same as for liquids and gases
E. zerci
A. absolute temperature
B. T2
C. T5
D. t
E. l/T
A. p = 0, x = 0 and a = 1
B. p= l,T = 0anda = 0
C. p = 0, x = 1 and a = 0
D. x = 0, a + p = 0
E. a = 0,x + p= 1.
where a = absorptivity, p == reflectivity, X = transmissivity
