# Hot hot heat

1. Homework Statement

the problem is one of understanding. if heat is incident on a surface raising the temperature to some number then conducts through the solid to the other side how much heat energy is actually at the other side?? i understand the temperatures will be different and that heat and temperature aren't the same thing but how could one calculate heat energy at the other side?

2. Homework Equations

i suppose the conduction equation Q = ((lambda*c.s.a)/length)*delta T)

q in equals a fraction of q out

3. The Attempt at a Solution

if i use the solar constant on the side a spacecraft around mars the temperatuere is around 30 degrees C i understand the temperature on the other side will be less and i know the incoming radiation so can work it out, but how much heat energy will be on the other side???

cheers all, this is really playing on my mind

What is 'heat energy'?

http://en.wikipedia.org/wiki/Heat

to quote "energy transferred from one body or system to another due to a difference in temperature"
If heat is the transfer of energy, how can one calculate the 'heat energy' at the other side? Surely, once the energy is at the other side it is no longer being transfered, and therefore the 'heat energy' is zero?

radiation conduction convection, all that jazz
