Q1:

The Stefan-Boltzman constant depends on the

A medium

B temperature

C surface

D none of these

ANS:D - none of these

The Stefan-Boltzmann constant (σ) is a fundamental physical constant that relates the total energy radiated per unit surface area of a black body to the fourth power of its absolute temperature. It is independent of the medium, surface, or any other specific properties of the radiating object. Therefore, the correct option is: none of these.
