Homework Statement
Let us assume that the earth, whose mean surface temperature may be taken to be
280 K, is in thermal equilibrium and radiates energy into space at the same rate that it
receives energy from the sun. If the Earth were moved to an orbit of twice its present
radius, what would be its expected mean surface temperature?
T = 280K
T' = ?
Homework Equations
T' = T (?)
The ? indicates that I have to multiply T by something, but I do not know where to start so I was hoping to have some help on where to start
The Attempt at a Solution
Don't know how to start this question, if someone could help, that would be great. I do know the answer however and it is 198K.
Thanks
