A 3.0 cm diameter spherical body has a temperature of 700°C that radiates as a perfect emitter. What is the rate in watts that the body radiates energy?
The entire surface of Earth receives an average of 430 W/m2 of heat flux from the Sun through radiation. What would be the temperature of Earths surface if it radiated like a black body? (The solution is 22°C)
The radiation energy (intensity of the radiation) reaching Earth from the sun at the top of the atmosphere is 1.36×103??2⁄, which is called the solar constant. Assuming that Earth absorbs the total power coming from the Sun to the Earth and radiates with the emissivity of 0.8 at a uniform temperature around the Earth, what would the equilibrium temperature of Earth be?

Your dark-adapted eye has a pupil diameter of about 7 mm and can detect light intensity down to about 1.5 x 10-11 W/m2. Assume the emissivity of the Sun is equal to 1. First, given these numbers, what is the surface temperature of the Sun in Kelvin to 3 significant digits? What is the power output of the Sun in moles of watts? (in other words, take the number of watts and divide it by Avogadro's number) Assuming that all of the Sun's power is given off as 500 nm photons*, how many photons are given off by the Sun every second?

The first understanding of this behavior was due to the Dutch physicist Peter Debye, who in 1912, treated atomic oscillations with the quantum theory that Max Planck had recently used for radiation. For instance, a good approximation for the specific heat of salt, NaCl, is c =3.33× 104 J ⎛ ⎞ kg·k ⎝ T 321 K ΘD, and the formula works well when ⎠ Tarrow_forward
