Homework Equations

energy=-u_0(B)[/B]

The Attempt at a Solution

According to the back of the book,
a. energy level separation increaess
b. mean energy decreases which makes sense since B is increasing then E must be increasing negatively.
c. negative (not too sure why this is the case)
d. increases
e. T increases[/B]

Hello there,

Thank you for your post. To answer your questions:

a. As B increases, the energy level separation increases because the energy levels are directly proportional to the magnetic field strength.
b. As you correctly stated, mean energy decreases because as B increases, the energy levels shift downwards. This results in a decrease in the average energy of the system.
c. The negative sign in the equation indicates that the energy is decreasing. This is because the energy is being pulled towards the lower energy levels as B increases.
d. The energy of the system increases as the magnetic field strength increases because the energy levels are directly proportional to B.
e. The temperature increases because as the energy levels get closer together, the system has more available energy states to occupy. This results in an increase in the temperature of the system.

I hope this helps clarify any confusion you may have had. Let me know if you have any further questions.
