Class 11 Geography: Atmospheric Humidity NCERT Solutions

Yeh content Class 11 NCERT 'Fundamentals of Physical Geography' ke Chapter 8 - 'Humidity and Precipitation' par aadharit hai. Yahaan hum atmoshpherik namī (humidity) ke basic concepts, formulas aur types ko Hinglish mein samjhenge.

Humidity Kya Hai?

Humidity se matlab hai havā mein maujood water vapor ki matrā. Yeh ek important atmospheric condition hai jo mausam ko prabhavit karti hai.

Atmospheric Humidity: NCERT Concepts and Solutions

Fundamentals of Physical Geography ke is chapter mein, humidity ke kayi important topics cover kiye gaye hain. In concepts ko examples ke saath samajhna important hai.

Humidity ke Types

Humidity ko mainly do categories mein divide kiya jata hai:

• Absolute Humidity: Yeh ek niyat volume ki havā (jaise 1 cubic meter) mein water vapor ke mass ko darshata hai. Isko gram per cubic meter mein measure karte hain.
• Relative Humidity: Yeh ek particular temperature par, havā mein present water vapor ki actual amount aur usi temperature par hold kar sakne wali maximum water vapor capacity ka anupaat hai. Isko percentage (%) mein express karte hain. Formula hai: (Actual Water Vapor / Maximum Capacity) × 100.

Humidity Measurement

Humidity ko measure karne ke liye alag-alag instruments ka prayog hota hai. Inmein se do pramukh hain:

• Hygrometer: Yeh instrument relative humidity ko measure karta hai.
• Psychrometer: Ismein do thermometers (dry bulb aur wet bulb) hote hain. Dono ke readings ke difference se humidity ka pata chalta hai.

Related Atmospheric Processes

Humidity se directly related kuch processes bhi hain jinhe samajhna zaroori hai.

Evaporation

Evaporation woh process hai jismein water liquid state se gaseous state (water vapor) mein convert hota hai. Yeh process humidity ko badhata hai. Evaporation ki speed temperature, wind speed, aur surface area par nirbhar karti hai.

Condensation and Dew Point

Jab water vapor thanda hokar phir se liquid ya solid (ice) mein badal jata hai, use condensation kehte hain. Woh particular temperature jis par havā apne maximum water vapor capacity ko achieve kar leti hai aur condensation shuru ho jati hai, use Dew Point kehte hain. Dew point temperature ke neeche, excess water vapor dew, fog, ya clouds ki shape mein nazar aata hai.

Important Factors Affecting Humidity

Kuch key factors humidity ko prabhavit karte hain:

• Temperature: Temperature badhne se water vapor hold karne ki capacity badh jaati hai, isliye relative humidity kam ho sakti hai.
• Water Bodies: Samandar ya bade talab ke nazdeek areas mein humidity zyada hoti hai kyunki evaporation source paas mein hota hai.
• Wind: Wind moisture wali havā ko ek jagah se doosri jagah le jaati hai.

NCERT Textbook ke Important Questions ke Liye Hints

Chapter ke end mein diye gaye questions ko solve karne ke liye, in points ko yaad rakhein:

• Absolute aur Relative Humidity mein antar samjhein.
• Dew point ki definition aur uska condensation se sambandh.
• Evaporation ko prabhavit karne wale factors ke naam likhna.
• Relative Humidity ka formula aur uski calculation.

Yeh sabhi concepts aapko chapter ko acche se samajhne aur CBSE board exams ke liye taiyari karne mein madad karenge.
