Question

3. Liquids have high density due to their molecules are tightly packed in a small volume. 4. The sea breeze in the coastal region blows at night. 5. The hot air in the rooms rises up and flows out of ventilators. The fresh and cold air from outside flows into room from doors and windows.​

Answer 1

Answer:

3. yes.

4. yes it is true

5. True.

3. Because density is directly proportional to the mass and inversely proportional to the volume . So as the volume decreases density increases and more molecules is getting fixed in the small volume

5. When you heat air it expends, therefore, it becomes less dense than other air around it and floats up above the more dense air.
