Consider N non-interacting diatomic molecules stuck on a metal surface. Each molecule can either lie flat on the surface, in whi
ch case it must be aligned to one of two directions, x and y, or it can stand up along the z direction. There is an energy cost e > 0 associated with a molecule standing up, and zero energy for molecules lying flat along x or y directions.
What are the possible energy levels for this system of N particles, and what is the number of microstates associated to each energy level?
Find the entropy and energy of the system as a function of the temperature, T.
What is the probability of a specific molecule standing up?
What is the largest possible value of the energy of the system at any temperature?

Answer:
Assuming the emissivity is 1.0, the temperature of the wood stove will be about 417 C
Explanation:
You can use the Stefan-Boltzmann formula tying energy with temperature of a blackbody:
P - rate of radiation
is the blackbody's emissivity
is the Stefan-Boltzmann constant
A - area
T - temperature
So,
Assuming the emissivity ( a number between 0 and 1) is 1.0, the temperature of the wood stove will be about 417 C. The emissivity number was not given in your question. If you determine what it is, you can divide this result by the fourth power of that value to get an updated result.
