Zoom physics 4 - phase change
At the end I got confused between release and absorption of heat energy. Condensation releases a lot of heat energy. For our air conditioning we have the 'condenser' outside (hot), and the evaporator inside absorbing heat (cold).
Okay so... I had to watch this one a few times, because this is kind of a different way of thinking about things.
When you talked about heat energy in evaporation is this the reason that AGW questioners state that water vapour is a "green house gas" example it has lots of heat energy. It seems to me it is.
I'm going to watch one more time still.. It's a different way of thinking about this stuff! But, I'm enjoying it :)
No. All the energy is taken up at the phase change. So, if the water vapour condenses into droplets, that's a lot of heat energy released. The phase change of water is what keeps us alive, and makes co2 irreverent. Venus is not a water planet.
