Class 6 Science Chapter 9: Methods of Separation in Everyday Life (Hinglish Notes)
Ye chapter 5 lines mein
Mixture mein do ya zyada padarth mile hote hain. Hum ise isliye alag karte hain taaki bekaar hissa hata sakein, ya do kaam ke hisse alag kar sakein. Tareeka is pe depend karta hai ki hisse kaise alag hain: solids ke liye handpicking, threshing, winnowing aur sieving; liquid mein na ghulne wale solid ke liye sedimentation, decantation aur filtration; ghule hue solid ke liye evaporation; dahi se makkhan ke liye churning; aur loha nikaalne ke liye magnet.
Mixture kya hai, aur use alag kyun karte hain?
Jab do ya zyada padarth mil jaate hain, to mixture banta hai: anaaj mein kankad, aate mein chokar, samudra ke paani mein namak. Chapter mein Malli aur Valli India ki yatra karte hain, Haryana se Ahmedabad, Puducherry, Bhopal aur Shillong tak, aur har jagah mixtures alag hote dekhte hain. Mixture do wajah se alag karte hain: bekaar hissa hataane ke liye, ya do kaam ke hisse alag karne ke liye. Tareeka is pe depend karta hai ki hisse kaise alag hain.
Handpicking aur threshing
Handpicking mein bekaar tukde haath se chunte hain, jaise gehun se chhote kankad aur bhoosa, size, rang aur shape ke fark se. Ye tab theek hai jab tukde kam hon aur aasaani se chune ja sakein. Threshing kati hui faslon ke danthal se daane alag karti hai, jaise danthal ko lakdi ke bade lathe pe peetkar. Dekho: handpicking, threshing aur winnowing.
Winnowing
Threshing ke baad daanon mein halka bhoosa mila hota hai. Kisan oonche chabootre pe khada hoke soop (baans ki tokri) ko hawa ki disha mein jhukaata hai. Halka bhoosa ud kar alag gir jaata hai aur bhaari daane seedhe neeche girte hain. Ye winnowing hai. Threshers naam ki machines threshing aur winnowing saath karti hain.
Sieving
Chhalni baarik kanon ko apne chhedon se nikalne deti hai aur bade kanon ko rok leti hai. Isse aate se chokar aur chhote kankad hatte hain, aur construction site pe ret se kankad alag hote hain. Sieving un solid–solid mixtures ke liye hai jinke kan alag size ke hon.
Evaporation
Paani mein ghula namak filter se nahi nikalta. Use wapas paane ke liye paani ko vapour bana ke hataate hain: ye evaporation hai, liquid ka vapour banna. Samudra ka paani uthle gaddhon mein dhoop aur hawa mein rakha jaata hai; kuch dinon mein paani ud jaata hai aur namak bach jaata hai, jise phir saaf kiya jaata hai. Vapour ko thanda karke condense karne se paani bhi wapas milta hai. Dekho: evaporation se namak alag karna.
Sedimentation, decantation aur filtration
Chai ke bartan ko bina hilaaye chhod do, to patti neeche baith jaati hai: ye sedimentation hai. Bartan jhuka ke chai nikaalna decantation hai, jisse tel aur paani bhi alag hote hain. Kuch pattiyan phir bhi aa jaati hain, isliye chhalni use karte hain: filtration. Kapde aur filter paper ke chhed aur chhote hote hain, isliye ye gande paani ko bhi saaf kar dete hain: keechad residue ke roop mein rukta hai aur saaf filtrate nikalta hai. Dekho: sedimentation, decantation aur filtration.
Churning aur magnetic separation
Bhopal mein ek painting mein ek aurat badi mathni se dahi math rahi hai. Halka makkhan upar aa jaata hai aur chhaach bach jaati hai. Shillong mein ek carpenter se lohe ki keelein buraade mein gir jaati hain; buraade mein magnet ghumaane se saari keelein chipak jaati hain. Magnet se loha jaise chumbakiya padarth alag karna magnetic separation hai. Recyclers crane pe lage magnets se kachre ke dher se lohe ka kabaad nikaalte hain.
Sahi tareeka kaise chunein
| Tareeka | Kis fark pe kaam karta hai | Example |
|---|---|---|
| Handpicking | Size, rang, shape | Anaaj se kankad |
| Winnowing | Wazan (halka aur bhaari) | Daanon se bhoosa |
| Sieving | Kanon ka size | Aate se chokar |
| Sedimentation aur decantation | Bhaari hissa neeche baithta hai | Chai ki patti, tel aur paani |
| Filtration | Filter ke chhedon ka size | Paani se keechad |
| Evaporation | Liquid udta hai, solid bachta hai | Samudra ke paani se namak |
| Churning | Makkhan halka hai | Dahi se makkhan |
| Magnetic separation | Magnet ki taraf kheenchav | Buraade se lohe ki keelein |
Kai hisson wale mixture ke liye aksar inme se kai tareeke, ek ke baad ek, lagte hain.
Key terms (zaroori shabd)
| Term | Matlab |
|---|---|
| Mixture (mishran) | Do ya zyada padarth mile hue, jaise anaaj mein kankad ya paani mein namak. |
| Handpicking | Mixture ka koi hissa haath se chunna, size, rang aur shape ke fark se. |
| Threshing | Kati hui faslon ke danthal peetkar unse daane alag karna. |
| Winnowing (phatakna) | Hawa ya phoonk se mixture ke halke aur bhaari hisse alag karna, jaise bhoosa aur daane. |
| Sieving (chhaanna) | Chhalni se alag-alag size ke solid kan alag karna, jaise aate se chokar. |
| Sedimentation | Liquid mein na ghulne wale bhaari hisse ka neeche baith jaana. |
| Decantation | Bartan ko jhuka ke liquid nikaalna, neeche baitha hissa chhod ke. |
| Filtration (chhaanna) | Filter se liquid mein se na ghulne wala solid alag karna. Filter pe bacha solid residue hai, aur nikla liquid filtrate. |
| Evaporation (vaashpeekaran) | Liquid ka vapour banna. Isse liquid mein ghula solid alag hota hai, jaise namak paani se. |
| Condensation (sanghanan) | Vapour ka wapas liquid banna, jisse paani bhi ikattha kar sakte hain. |
| Churning (mathna) | Dahi ko mathni se tezi se mathna taaki halka makkhan alag hoke upar aa jaaye. |
| Magnetic separation | Magnet se loha jaise chumbakiya padarthon ko baaki se alag karna. |
