Answer
35 g kwa 100 g ya maji
Haya hapa majibu ya maswali uliyotuma:
18. i) Step 1: Pata masi ya solid P kavu. Masi ya solid P kavu = (Masi ya chombo cha kuyeyushia + solid P kavu) - (Masi ya chombo cha kuyeyushia tupu)
Step 2: Pata masi ya maji katika mmumunyo uliokolea. Masi ya mmumunyo uliokolea = (Masi ya chombo cha kuyeyushia + mmumunyo uliokolea) - (Masi ya chombo cha kuyeyushia tupu) Masi ya maji = Masi ya mmumunyo uliokolea - Masi ya solid P kavu
Step 3: Kokotoa umumunyifu wa solid P kwa 100 g ya maji. Umumunyifu = Umumunyifu wa solid P ni .
18. ii) Tahadhari moja iliyozingatiwa ni: • Pasha moto kwa upole ili kuzuia mchanganyiko kutapakaa.
19. i) Hali mbili zinazoharakisha kutu ni: • Kuwepo kwa maji ya chumvi. • Joto la juu.
19. ii) Njia mbili za kuzuia kutu ni: • Kupaka rangi. • Kupaka mafuta/grisi.
20. i) Mchakato ulioonyeshwa na mlinganyo hapo juu unaitwa: • Ufaaji (Cracking).
