Question
10: If star A has a temperature of
4000 Kelvin and star B has a temperature of twice that, or 8000 Kelvin,
how much more energy does it radiate per second than star A?
From the
Steffan-Boltzmann Law (E = σT4), we know that for the radiated energy, E goes as T to the 4th power, so 24
= 16 times
