Harorat birligini konvertatsiya qilish bo'yicha savollarga misol

Harorat birligini o'zgartirish muammolariga 5 ta misol

1. Jismning harorati 122°F ga teng, Selsiy shkalasi bo'yicha o'lchanganda...

A. 323°C

B. 122°C

C. 50°C

D. 40°C

Munozara

Harorat shkalasini Farengeytdan Selsiygacha o'tkazish formulasi:

T _C = 5/9 (T _F – 32)

Tavsif: T_C = Selsiy shkalasida harorat, T_F = Farengeyt shkalasidagi harorat

Selsiy shkalasida harorat quyidagicha:

T _C = 5/9 (122 – 32) = T _C = 5/9 (90) = 5 (10)

T _C = 50 ^° C

To'g'ri javob C.

2. Bolada isitma bor, ikkita shkalali termometr bilan o'lchanganda, Selsiy shkalasi bo'yicha ko'rsatilgan raqam 40° ga teng, keyin Reamur shkalasida ko'rsatilgan raqam...

A. 31 °R

B. 32 °R

C. 45 °R

D. 50°R

Munozara

Ma'lumki:

Selsiy shkalasida harorat (T) ^oC) = 40

So'ralgan: Reamur shkalasi bo'yicha harorat (T) ^oR)

Javob:

Toza suvning qaynash harorati (H)₂O) = 100 ^oC = 80 ^oR

Toza suvning muzlash nuqtasi harorati (H)₂O) = 0 ^oC = 0 ^oR

Tselsiy bo'yicha Reamur shkalasiga aylantirish formulasi:

T ^oR = (80/100) T ^oC

T ^oR = (4/5) T ^oC

T ^oR = (4/5) 40

T ^oR = (4)(8)

T ^oR = 32 ^oR

To'g'ri javob B.

3. Yon tomondagi termometr rasmiga qarang! Selsiy termometr shkalasidagi Y harorati…

A. 172 ^oC
B. 108 ^oC
C. 60 ^oC
D. 44 ^oC

Munozara

Ma'lumki:
Farengeyt shkalasi = 140 ^oF
So'ralgan: Selsiy shkalasi
Javob:

Farengeyt shkalasini Selsiy shkalasiga o'tkazish formulasi:
T ^oC = 5/9 (T ^oF – 32)
Selsiy shkalasi:
T ^oC = 5/9 (140 – 32)
T ^oC = 5/9 (108)
T ^oC = 540/9
T ^oC = 60
To'g'ri javob C.

4.

Quyidagi harorat o'lchovlariga e'tibor bering! Farengeyt termometridagi Y qiymati…

A. 54 ^oF
B. 65 ^oF
C. 76 ^oF
D. 86 ^oF

Munozara
Ma'lumki:
Selsiy shkalasi = 30 ^oC
Savol berildi: Farengeyt shkalasi
Javob:
Selsiy shkalasini Farengeyt shkalasiga o'tkazish formulasi:
T ^oF = (9/5)(T) ^oC) + 32
Farengeyt shkalasi:
T ^oF = (9/5)(30) + 32
T ^oF = (270/5) + 32
T ^oF = 54 + 32
T ^oF = 86 yil
To'g'ri javob D.

5. Quyidagi haroratni o'lchash rasmiga qarang! Farengeyt termometri haroratni ko'rsatadi….
A. 92 ^oF
B. 108 ^oF
C. 122 ^oF
D. 140 ^oF
Munozara
Ma'lumki:
Selsiy shkalasi = 60 ^oC
Savol berildi: Farengeyt shkalasi
Javob:
Selsiy shkalasini Farengeyt shkalasiga o'tkazish formulasi:
T ^oF = (9/5)(T) ^oC) + 32
Farengeyt shkalasi:
T ^oF = (9/5)(60) + 32
T ^oF = (9)(12) + 32
T ^oF = 108 + 32
T ^oF = 140 yil
To'g'ri javob D.
