  1. Hi, Can somebody help me with this question please? In humid air with a water content of 3 g / (kg dry air), liquid water is injected at a temperature of 30 ° C, after which the air temperature becomes 18 ° C and its relative humidity 50%. The total pressure is constant 1.013 bar and the mass of the dry air is 60 kg. Calculate: a) the amount of water injected; b )the air temperature before water is injected
  2. Kalstein sucks and you should never ever buy a water purification system or anything else from them.
  3. Not the exact temperature but.. I've been wondering There has been some debate on the internet about room temperature or cold water being better for you body (im sure its all pseudo science nonsense) But it did get me thinking. The springs humans have been drinking out of for throughout history on this planet.. Are most of them pretty cold? Do we have an evolutionary preference for cold water? I have never really been to a spring to gather my own water. Are they usually pretty cold?
  4. Now to us, we first thought that life would need water, and the sun, along with organics to feed on. But how are we so sure about it? Life can't be so hard to make, and needs the exact process that earth went through. Such as we thought that life needs photosynthesis to live. But when we look at the Movile Cave, we find that the beasts that live down there, use chemosynthesis instead of photosynthesis. So what does this mean? It means that we really don't need the sun for life. In fact, I'm sure that if Pluto had a bigger atmosphere to retain more heat, and the liquid water mountains melted, t
