Question 1
According to the Stefan-Boltzmann law, if the absolute temperature of a blackbody emitter increases from 300 K (26.85°C) to 600 K (326.85°C), by what factor does total radiant emittance increase?
Correct Answer:
16 times
Question 2
Using Wien's Displacement Law (lambda_max * T = 2898 um*K), at what peak wavelength does an object at 500 K (226.85°C) emit its maximum spectral radiance?
Correct Answer:
5.796 um
Question 3
For an opaque body (transmissivity tau = 0) in thermal equilibrium, what is the mathematical relationship between emissivity (epsilon) and reflectivity (rho) under Kirchhoff's Law?
Correct Answer:
epsilon + rho = 1
Question 4
Heat conduction through a flat wall is described by Fourier's Law (Q = k * A * delta_T / d). If wall thickness d is halved while surface temperature difference delta_T remains constant, how does conductive heat flux change?
Correct Answer:
Heat flux doubles
Question 5
During an outdoor electrical thermographic inspection, wind speed increases from 1 m/s (breeze) to 5 m/s. What effect does this have on observed electrical anomaly surface temperatures?
Correct Answer:
Apparent surface temperature of the hotspot decreases significantly due to forced convection
