Harorat shkalasini o'zgartirish bo'yicha 6 ta savolga misollar: Selsiy shkalasi, Farengeyt shkalasi, Kelvin shkalasi

1. 50^oC = ….. ^oF ?
Munozara
1 atmosfera havo bosimida Selsiy termometri uchun muz nuqtasi harorati 0 ga teng^oC, holbuki termometr Farengeyt shkalasi 32 ga teng^oF. 1 atmosfera havo bosimida Selsiy termometri uchun bug 'nuqtasi harorati 100 ga teng^oC, Farengeyt shkalasi bo'yicha termometr esa 212 ga teng^oF.
Shunday qilib, 0^oC = 32^oF va 100^oC = 212^oF.

^{Selsiy shkalasida 0 °} C va 100 ^° C orasida 100 ^daraja mavjud . Farengeyt shkalasida 32 ^° F va 212 ^° F orasida 180 ^daraja mavjud . Farengeyt haroratini (T ^° F) olish uchun avval Selsiy haroratini (T ^° C) 9/5 ga ko'paytiring va keyin 32 ^{darajani qo'shing.}

T^oF = (180/100) T^oC + 32
T^oF = (9/5) T^oC + 32
T^oF = (9/5) 50 + 32
T^oF = (9) 10 + 32
T^oF = 90 + 32
T^oF = 122 yil

50 ^° C = 122 ^° F

2. 86^oF = ….. ^oC ?
Munozara
Selsiy shkalasida haroratni olish uchun (T)^oC), Farengeyt shkalasida haroratni 32 ga kamaytiring (T^oF – 32) ni 5/9 ga ko'paytiring.

T^oC = (100/180)(T)^oF – 32)
T^oC = (5/9)(T)^oF – 32)
T^oC = (5/9)(86 – 32)
T^oC = (5/9)(54)
T^oC = (5)(6)
T^oC = 30

86 ^{o Farengeyt 30 o} Selsiyga teng

3. 50^oC = ….. K ?
Munozara
T = T ^oC + 273
T = 50 + 273
T = 323

50 oC = 323 Kelvin

4. 212^oF = ….. K ?
Munozara
Farengeyt shkalasidagi haroratni Selsiy shkalasiga, keyin esa Selsiy shkalasidagi haroratni Kelvin shkalasiga o'tkazing.
T^oC = (100/180)(T)^oF – 32)
T^oC = (5/9)(T)^oF – 32)
T^oC = (5/9)(212 – 32)
T^oC = (5/9)(180)
T^oC = (5)(20)
T^oC = 100

212 ^{o Farengeyt 100 o} Selsiyga teng

T = 100 + 273
T = 373 Kelvin

6. Talaba rasmda ko'rsatilgandek ikkita termometr yordamida suv haroratini o'lchaydi. Agar Selsiy termometrida o'lchangan suv harorati rasmda ko'rsatilgandek bo'lsa, Farengeyt termometridagi harorat….

A. 60^oF

B. 108 ^o F

C. 140 ^o F

D. 172 ^o F

Munozara

Selsiy termometri uchun muz nuqtasi harorati 0 ^o C, Farengeyt termometri uchun esa 32 ^o F. Selsiy termometri uchun bugʻ nuqtasi harorati 100 ^o C, Farengeyt termometri uchun esa 212 ^o F.

Demak, 0 ^° C = 32 ^° F va 100 ^° C = 212 ^° F.

Selsiy shkalasi bo'yicha, 0 oralig'ida^oC dan 100 gacha^oC tarkibida 100 ta bor^o. Farengeyt shkalasi bo'yicha, 32 orasida^oF dan 212 gacha^oF tarkibida 180 ta bor^o. Farengeyt shkalasida haroratni olish uchun (T)^oF), avval haroratni Selsiy shkalasida ko'paytiring (T^oC) 9/5 bilan, keyin 32 ni qo'shing^o

^{F dan} F gacha = (180/100) C ^dan + 32 gacha

^{F dan} F gacha = (9/5) C ^dan C gacha + 32 gacha

^{F dan} F gacha = (9/5) 60 + 32 gacha

^{F ga} = (9) 12 + 32 gacha

^{F dan} F gacha = 108 + 32 gacha

^{F dan} F gacha = 140 gacha

60 ^° C = 140 ^° F

To'g'ri javob C.
