For a certain material, the values of transmissivity and reflectivity are specified as 0.88 and 0.07, respectively. The absorptivity of that material is .
-
A.
0.88
-
B.
1
-
C.
0.05
-
D.
0.07
Correct Answer:
C. 0.05
Explanation:
In thermodynamics, the sum of a material's transmissivity, reflectivity, and absorptivity must equal one (1 = α + ρ + τ). Given a transmissivity of 0.88 and a reflectivity of 0.07, the absorptivity is calculated by subtracting these values from the total (1 - 0.88 - 0.07), which results in 0.05.
