1) What is thermal equilibrium? Is the Sun in thermal equilibrium? How do we know this?
2) In order to maintain thermal equilibrium, how much energy must the Sun generate every second?
Tutorial
Star A has a temperature of 5,000 K. How much energy per second (in J/s/m2) does it radiate from a square meter of its surface?
If the temperature of Star A decreases by a factor of 2, the energy will decrease by a factor of
Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate from a square meter of its surface?
Part 1 of 4
The energy of a star is related to its temperature by
E = GT4
where σ = 5.67 x 10-8 J/s/m2/K4.
Part 2 of 4
To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA.
EA =
J/s/m²

Imagine a giant sphere with a radius of 1 AU surrounding the Sun. What is the surface area of this sphere, in square meters? (Hint: The formula for the surface area of a sphere is 4rr2.) b. Because this imaginary giant sphere surrounds the Sun, the Sun's entire luminosity of 3.8 × 1020 watts must pass through it. Calculate the power passing through each square meter of this imaginary sphere in watts per square meter. Explain why this number represents the maximum power per square meter that a solar collector in Earth orbit can collect. c.
