Evaporation aur condensation kya hai?

Paani kahan chala jaata hai?

Baarish ke baad playground puddles se bhar jaata hai. Shaam tak bahut se puddle chhote ho jaate hain. Dhuli plates aur glass rack pe sookh jaate hain. Paani gaya kahan?

Ek idea ye hai ki paani zameen mein samaa gaya. Puddle ke liye ye kuch had tak sahi hai, par plate ke liye nahi. Test karo: steel ki plate pe ek chammach paani rakho aur har kuch minute mein plate ke neeche dekho. Neeche ka hissa sookha rehta hai, phir bhi paani dheere-dheere gayab ho jaata hai. Wo rish ke nahi gaya. Wo ek na dikhne wali gas, water vapour, ban ke hawa mein chala gaya.

Paani ke water vapour banne ko evaporation kehte hain. Ye hamesha chalta rehta hai, room temperature pe bhi. Isi se geele kapde, pocha laga farsh aur hamari skin ka paseena sookhte hain. Hand sanitiser haath pe ragadte hi isi wajah se gayab ho jaata hai: wo evaporate hota hai.

Kya steam aur water vapour ek hi hain?

Dosa banate waqt garam tawe pe paani ki kuch boondein chhidko, to wo chhan-chhan ki aawaaz ke saath steam ban ke gayab ho jaati hain. Steam garam paani se nikalti water vapour hai. Water vapour khud dikhti nahi. Steam safed isliye dikhti hai kyunki kuch vapour jaldi thandi hoke paani ki chhoti boondein ban jaati hai, aur wahi boondein dikhti hain.

Thande glass pe boondein kahan se aati hain?

Glass mein thanda paani aur kuch ice cubes daalo, aur paanch minute ruko. Glass ke bahar boondein aa jaati hain, jo dheere-dheere milkar badi boondein ban jaati hain. Kya paani glass se rish ke bahar aaya?

Scientist ki tarah check karo:

1. Paani ka level mark karo marker ya tape se. Level neeche nahi jaata, yaani glass se paani bahar nahi ja raha.
2. Weight naapo. Glass ko ek chhoti plate se dhak ke digital balance pe rakho aur aadhe ghante tak har paanch minute mein reading likho. Reading badhti hai. Extra paani bahar se aa raha hai.

Ye extra paani hawa se aata hai. Hawa mein hamesha kuch water vapour hoti hai. Jab wo vapour thande glass ko chhooti hai, to thandi hoke wapas liquid paani ban jaati hai. Water vapour ke liquid paani banne ko condensation kehte hain.

Condensation aur jagah bhi dikhta hai:

• Subah ghaas aur patton pe os ki boondein.
• Ubalte paani ke bartan pe rakhe dhakkan ke neeche boondein.
• Garam paani se nahaane ke baad dhundhla sheesha.

Humidity kya hai?

Hawa mein water vapour ki maatra ko humidity kehte hain. Baarish wale din humidity zyada hoti hai. Akhbaar roz tumhare ilaake ki humidity batate hain. Atmospheric Water Generator (AWG) machines nami wali hawa ko thanda karti hain taaki uski water vapour condense ho jaaye, aur us paani ko peene ke liye ikattha karti hain, bilkul thande glass ki boondon ki tarah.

Evaporation aur condensation se baarish kaise hoti hai?

Suraj samudra, nadiyon, jheelon aur zameen ko garam karta hai, aur unka paani evaporate hota hai. Water vapour hawa se halki hoti hai, isliye upar uthti hai. Jitna upar jaao, hawa utni thandi hoti hai. Ek oonchaai pe vapour chhoti boondon mein condense ho jaati hai, aksar dhool ke kanon ke aas-paas. Hawa mein tairti bahut saari boondein milkar baadal banati hain. Jab boondein judkar itni bhaari ho jaati hain ki tair na sakein, to baarish ban ke girti hain, aur khaas haalaat mein ole ya barf ban ke.

Kisi bade ki madad se ek bottle mein chhota baadal bana sakte ho. Khaali plastic bottle mein thoda paani daalo, dhool ke liye jale kaagaz ka chhota tukda daalo, dhakkan band karo, aur bottle ko baar-baar dabao aur chhodo. Paani ke upar ek dhundh, yaani chhota sa baadal, dikhne lagta hai.

Water cycle kya hai?

Baarish aur pighli barf ka paani nadiyon aur jheelon mein jaata hai ya zameen mein samaa ke groundwater banta hai, aur zyadatar paani wapas samudra tak pahunchta hai. Phir wo dobara evaporate hota hai. Dharti ki sateh aur hawa ke beech paani ke is lagaataar ghoomne ko water cycle kehte hain.

Dharti ke saare paani ka sirf chhota hissa hi paudhon, jaanwaron aur insaanon ke kaam ka hai; zyadatar paani samudra mein hai. Isliye paani soch-samajh ke use karo aur nadiyon-jheelon ko saaf rakho. Paani jaldi kis cheez se sookhta hai, ye jaanne ke liye padho evaporation ke factors, ya paani ki teen states dobara dekho.
