Question

Consider the following statements and identify the right ones.
i) The temperature of the air rises when its pressure falls.
ii) The pressure of the air falls when the temperature rises.

• A. i only
• B. ii only
• C. Both of these
• D. None of these

Answer 1

The correct option is D None of these

As air warms up, the molecules in the air become more active and they use up more individual space. This leads to a rise in the air pressure. Similarly, when the air cools down the molecules remain compact, leading to a decrease in air pressure.
