3. Ish natijasini ko‘rib chiqing.
3.1. Issiqlikdan kengayish β o‘rtacha koeffitsienti 3-jadvaldan topib, hisoblash kerak.
3.2. (5.3) formula orqali kerakli hisobotlarni olib boring va № 1-1; № 1-2; va № 1-3 eritmalarni zichligini takror ishlab chiqarilgan natijalarni tekshiring, natijalarni 2-jadvalga yozing.
Eritmalarning xarorat qiymatlari (⁰S) 1-jadval

Eritma	t1	t2	t3	to‘r	Eslatma
1-1 1-2 1-3 2 3

Sut yog‘ligining qiymatlari 2-jadval

Eritma	Rt1	Rt2	Rt3	Ro‘r	Eslatma
1-1 1-2 1-3 2 3

NaCL suvli eritmaning issiqlikdan kengayish koeffitsienti, β*10⁴ (1/ ⁰K)
3-jadval

Eritmaning konsentratsiyasi	t=10 ^0S	t=20 ^0S	t=30 ^0S t3	t=40 ^0S to‘r
10% 15% 20%	1,9 2,8 4,0	1,9 2,8 4,5	2,0 2,9 4,9	2,0 2,9 5,4

Olingan ma’lumotlar asosida hisobot tayyorlash
Hisobotda quyidagilar bo‘lishi kerak:
1. Ishdan maqsad
2. Hisoblash formulasi
3. Ishning o‘tkazish uslubi
4. Kuzatishlarning natijalari (1-jadval va 2- jadval)
