Explain the following:
A toy balloon filled with hydrogen rises to the ceilling, but if filled with carbon dioxide sinks to the floor.

Text Solution

Verified by Experts

Density of hydrogen `lt lt` density of carbon dioxide. So, when a balloon is filled with hydrogen, the weight of the air displaced is becomes more than the weight of a gas filled balloon and hence, the balloon rises to the ceiling. But when the balloon is filled with carbon dioxide, the weight of the air displaced becomes less than the weight of a gas filled balloon and hence, the balloon sink to the floor.
