Consider two days wh*2 l6k qy4f.uo)nult wen the air temperl)cbps/ u378vjwp.yp ature is the same but the humidity is different. Whic.l7wp3yuspcv )p8 b j/h is more dense, the dry air or the humid air at the same T? Explain.
参考答案: On a day when the relative
humidity is high, the percentage of air molecules that are water (as opposed to
$N_2$ or $O_2$ molecules) is increased.
Since the molecular mass of water is less than that of either $N_2$ or $O_2$,
the average mass of air molecules in a given volume will decrease, and thus the
density will be lower for the humid air.
