Question

How can you apply a correction for the loss of heat due to radiation?

Answer 1

It is known that radiated heat is proportional

P = K*T^4

This Stefan–Boltzmann law, T is absolute temperature of the body, K is constant.

I guess the question is related to the fact that usually that body stays not in absolute vacuum in some environment which has another temperature T0. Then, we can note that in thermal equilibrium (when the body is also at T0) it radiates and receives same amount of radiation. So it receives K*T0^4 from the environment.

Ptotal (T=T0) = 0 = K*T0^4 - K*T0^4

Then, when T <> T0 we have

Ptotal = -K*T0^4 + K*T^4 = K ( T^4 - T0^4)

when the temperature difference is small T - To << T0

Ptotal = K ( T^4 - T0^4) = ~ 4*K* (T-T0)

Answer 2

Answer:

Heat loss due to conduction is prevented by placing the calariometer box in a well lagged vessel using wool or cork material. heat loss due to convection is prevented by placing a lid on

the box.
