  1. Water vapor will hold in the heat  (like the clouds do)


  2. How  a cold room  then   speak  about  the same temperature

  3. because the water vapour makes the air transmit heat more effectively (as it can absorb more energy per unit volume - specific heat) that makes it feel colder as you are losing heat more rapidly.

  4. In a cold dry room moisture from your body will evaporate from the surface of your skin lowering your skin temperature and making you colder. In a normal cold room the high humidity restricts the evaporation of skin moisture, keeping you warmer.
