Huu hapa ni ufumbuzi wa maswali yako: a) J: Maji H: Mafuta ya kupikia b) Kukamilisha jedwali: SUBSTANCE — INITIAL VOLUME — MEASUREMENTS ON SYRINGE — FINAL VOLUME OBTAINED — VOLUME LEFT ON INTERFACEWater — 50 ml — (Syringe shows 10 ml remaining) — 50 ml − 10 ml = 40 ml — 50 ml − 40 ml = 10 ml; Kerosene — 50 ml — (Syringe shows 15 ml remaining) — 50 ml − 15 ml = 35 ml — 50 ml − 35 ml = 15 ml c) Step 1: Tambua kiasi cha maji kilichobaki kwenye kiolesura. Kiasi cha maji kilichobaki kwenye kiolesura ni 10 ml. Step 2: Tambua kiasi cha mafuta ya taa kilichobaki kwenye kiolesura. Kiasi cha mafuta ya taa kilichobaki kwenye kiolesura ni 15 ml. Step 3: Hesabu jumla ya kiasi cha kiolesura cha mafuta na maji. Jumla ya kiasi cha kiolesura = Kiasi cha maji kilichobaki + Kiasi cha mafuta ya taa kilichobaki; = 10 ml + 15 ml; = 25 ml d) Sababu kuu ni kwamba maji na mafuta hayachanganyikani (ni immiscible) na yana msongamano tofauti. Hii inasababisha kutengeneza tabaka tofauti, na hivyo kuruhusu kutenganishwa kwa urahisi kwa kutumia njia ya kutenganisha.
