Heat Transfer

Q1:

The energy radiated from a surface Q at absolute temperature T is related as

A Q ∝ T2

B Q ∝ T4

C Q ∝ T3

D none of these

ANS:B - Q ∝ T4

The energy radiated from a surface Q at absolute temperature T is related by Stefan-Boltzmann's law, which states that the total energy radiated per unit surface area of the surface is proportional to the fourth power of its absolute temperature (T). Mathematically, it is represented as: 4Q∝T4 So, the correct relationship is: 4Q∝T4
