Question

a clay pot at room temperature is placed in a kiln, and the pot's temperature doubles. How much more heat per second is the pot radiating when hot compared to when cool?

Answer 1

16 times

Step-by-step explanation:

According to stefan Boltzman law

E∝T^4

Heat radiated by a body is proportional to 4th power of absolute temperature. So, if the temperature becomes double the heat radiated will become 2^4 = 16 times.
