4) Which of the following gases is most unsuitable for filling up weather observation balloons.
4) Which of the following gases is most unsuitable for filling up weather observation balloons.
The correct option is D argon
Explanation for the correct option:
Weather observations balloons are those balloons which are filled with gas and thus reaches up high in the air, and helps to forecast weather conditions. These balloons require gases to be filled that are lighter than air, so that it may go up.
(D) Argon gas is heavier than air, hence cannot be used to fill weather observation balloons, as it does not allows the balloons to reach greater heights.
Explanation for the incorrect option -
(A) Helium is used to fill weather observation balloons as it is light weight gas.
(B) Neon is a light weight gas, hence can be used in weather observation balloons
(C) Hydrogen gas is the lightest gas of all, hence can be used in weather observation balloons.
Hence, the correct option is (D).
