Question

Hot air being less dense rises up.

• A. True
• B. False

Answer 1

The correct option is A True

1. The density of fluids decreased when it gets heated up.
2. When the air becomes hot its density decreases and hence, it rises up.
3. The density of cold air is high and hence it settles down.
4. This leads to the setup of conventional current.
5. Thus, hot air being less dense rises up.
   Hence, the given statement is true.
