Thermal Radiation and Heat Engines

AI Thread Summary
A solid hot body in outer space will emit black-body radiation as it cools down. It will not reach absolute zero but will instead approach thermal equilibrium with its surroundings. The surrounding space temperature, approximately 4K, will be the equilibrium point. Therefore, the body will continue to radiate heat until it matches the temperature of space. This process highlights the importance of the surrounding environment in thermal dynamics.

Hey all,

This is a simple question:

Lets say we have a solid hot-body in outer-space that's emitting thermal radiation. Assuming that it doesn't sublimate, will it simply radiate black-body radiation until it reaches absolute zero? This doesn't sound right.

Thanks

well outerspace isn't absolute zero, i would assume it would reach equilibrium by radiating its heat. at that point it would be the temperature of space (somewhere like 4K i think)
 
Thks!
 
I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
