    Homework answer by aman pandey - Proof 1 When we take ice in a glass and keep it at room temperature the water vapour present in the atmosphere condenses and it is visible as water droplets on the glass. This proves that their is water vapour present in the atmosphere. Proof 2 When we put water in a glass and keep it out on a dry day evapouration is farter and when we do this same experiment in the rainy season when the atmosphere is humid then the evapouration takes a lot of time. This shows that there is already lots of water vapour in the atmosphere and that's why there is less space for more water vapour and it takes a lot of time for it to get evapourated.

    Mam home work ka answer take a ice cubes and keep it in an open place to for some time. You will notice that around the beaker there are some water droplets.this droplets formed are due to condensation of water vapour around the beaker. This confirms the presence of water vapour in the air
    AND THANKS YOU SO MUCH MAM ❤

  • @sadafsamreen9515
    @sadafsamreen9515 10 месяцев назад +13

    answer to the question
    when a chilled water bottle is kept at room temp. one can notice droplets of water on the body of the bottle as the water vapour present in the atmosphere condenses as it strikes the bottle

    • @raghavsharma80
      @raghavsharma80 3 месяца назад +2

      correct

    • @ryuniivrceofficial
      @ryuniivrceofficial 2 месяца назад

      Yes because the room temperature would considered high for a water that is chilled or frozen since it would remain at its original position only when the temperature of surroundings is equal to the temperature of the chilled water itself, so that is why one can notice vapours on the edges of the bottle when it is kept at a room temperature.

    the shape of ice is tertahedral and till 4 degree the density increases below 4 the density decreases. therefore ice gets less density than water and ice floats on water

    In summer when we keep water in glas it take time to evaporate and if we keep water in glas in rainy season when it is humid then the evaporation become very slow hence proved that in atmosphere there is water vapour

    We can put ice in a glass of water at room temperature and we will be able to observe water droplets form on the surface of the glass
    This proves that atmosphere has water vapour in it.
