प्रश्न
What effect does temperature have on air pressure?
Advertisements
उत्तर
- Temperature and air pressure are closely related.
- Whenever the temperature is high, the air pressure is low.
- As the temperature rises, the air gets heated, expands, and becomes lighter.
- This lighter air in the vicinity of the earth's surface starts moving upwards in the sky. As a result, the air pressure in such areas decreases.
