A question about heat transfer in our atmosphere

AI Thread Summary
Radiation is identified as the primary method for decreasing the internal energy of the atmosphere. In kinetic theory, air molecules behave like bouncy balls, retaining kinetic energy when in contact with the vacuum of space. While some atmospheric gas does evaporate into space, this effect is minimal compared to the cooling achieved through radiation. The discussion emphasizes the significance of radiative energy loss in regulating atmospheric temperature. Overall, radiation plays a crucial role in the energy dynamics of the atmosphere.

So I've been wondering this for a couple days now: Is radiation the only means for decreasing the internal energy of our atmosphere?

I know that in kinetic theory the molecules are similar to bouncy balls and if they were in contact with the vacuum of space, the air molecules would have no reason to lose any of their kinetic energy, right?

There is a small amount of gas from the atmosphere evaporating into space, cooling off the atmosphere. But this is negligible compared to the radiative energy.

Thread 'Condensate rate of water for an air conditioning cooling coil'

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...
