The value of Stefan Boltzmann's constant in kcal-m²-hr-K⁴ is

Question

Quizplus · Accepted Answer

Stefan Boltzmann's constant is 5.67 x 10^-8 W/m²K⁴. To convert this to kcal-m²-hr-K⁴, we need to multiply by the following conversion factors:1 kcal = 4.184 kJ1 hr = 3600 s1 W = 1 J/sTherefore, 5.67 x 10^-8 W/m²K⁴ = 5.67 x 10^-8 J/m²sK⁴ = 5.67 x 10^-8 x 4.184 kJ/m²sK⁴ = 5.67 x 10^-8 x 4.184 x 10³ kcal/m²hrK⁴ = 2.37 x 10^-4 kcal/m²hrK⁴.Therefore, the correct answer is C) 4.87 x 10^-8.
