There are three modes of heat transfer: conduction, convection, and radiation. Each has an empirical law that relates the rate of heat transfer, q (W), to a temperature difference driving force. The rate law for radiation is known as the Stefan-Boltzmann Law. For a black-body, the Stefan-Boltzmann Law is: 9 = 0A(T4 - T) In this equation, q is the rate of heat transfer (W), σ is the Stefan-Boltzmann constant, A is the area (m²), T is the temperature of the material, and Tsurr is the temperature of the surroundings. Can the constant a change signs depnding on its units?

Question
Help with the following question. Which of the temperature scales in common use can be used directly in the Stefan-Boltzmann law? 
Transcribed Image Text:There are three modes of heat transfer: conduction, convection, and radiation. Each has an empirical law that relates the rate of heat
transfer, q (W), to a temperature difference driving force. The rate law for radiation is known as the Stefan-Boltzmann Law. For a
black-body, the Stefan-Boltzmann Law is:
9 = 0A(T4 - T)
In this equation, q is the rate of heat transfer (W), σ is the Stefan-Boltzmann constant, A is the area (m²), T is the temperature of the
material, and Tsurr is the temperature of the surroundings.
