What is the relative humidity of an air mass that has just produced rain?

4) repetitive change

It is given the initial temperature and the initial pressure, as well as the final pressure. it left for us to find only the final temperature. we can use the following formula: p₁/t₁=p₂/t₂  ⇔ 0.96atm/25ºc=1.25atm/x  ⇔ x=  ⇔ x≈32.6ºcbe careful to do any conversions  that might be needed, in this case, it wasn't necessary because the units were all in conformity with each other.

Ibelieve this is the answer:     evolution has no "goal". it is "simply" the survival of the fittest under a given condition. what should be the advantage of living longer? getting kids (=spreading the own genetic information) is done latest until the mid-40s after that we have not much biological meaning.  in addition,  not only does evolution not have a "goal," evolution doesn't necessarily mean "make us better! " it's absolutely possible to evolve negative traits.    hpe i could : )
