Zoya ki teacher mez par 12 cheezein rakhti hain aur class se sort karne ko kehti hain. Ek group padaarth se sort karta hai, doosra aakaar se, teesra kis kaam aati hain se. Sab sahi hain, bas batayein kaunsa gun use kiya!
Padaarthon ko group karne se hum unki tulna, gun yaad aur kaam ke liye sahi chunaav kar paate hain. Scientists padaarthon ko sakhti, chamak, roshni ka aar-paar jaana, ghulna aur tairna jaise gunon se group karte hain.
Ek hi padaarth alag groups mein aa sakta hai: kaanch sakht, paardarshi hai aur paani mein doobta hai. Isliye grouping hamesha chune gaye gun par nirbhar hai.

Inhe do alag tareekon se do groups mein baanto: steel chammach, lakdi ki chammach, kaanch ki goli, rubber gend, kaagaz ki naav, lohe ki keel.
Ek answer
Tairne se: lakdi ki chammach, rubber gend aur kaagaz ki naav tairti hain; baaki doobti hain. Chamak se: steel chammach, lohe ki keel (nayi) aur kaanch ki goli chamakti hain; baaki nahi. Doosri grouping bhi sahi hain.
