Kuchinja tembiricha

Zviyero zveCelsius neFahrenheit zviyero zvakasiyana zvekupisa. Kana tembiricha yechinhu ikayerwa uye ikataurwa muCelsius uye tobva tada kuratidza tembiricha yechinhu muFahrenheit, tinoshandura kubva kuCelsius kuenda kuFahrenheit. Muchikamu chino, tinodzidza maitiro ekushandura kana kuita shanduko dzetembiricha.

Pakumanikidzwa kwe1 atm, tembiricha yechando yethermometer yeCelsius = 0 ^oC, nepo chikero chethermometer cheFahrenheit = 32 ^oF. Kusiyana neizvi, pakumanikidzwa kwe1 atm, tembiricha yehutsi hwethermometer yechikero cheCelsius = 100 ^oC, nepo chikero chethermometer cheFahrenheit = 212 ^oF. Tarisa mufananidzo uri pazasi!

Kuti zvive nyore kwauri kushandura chikero cheCelsius kuita chikero cheFahrenheit kana kushandura chikero cheFahrenheit kuita chikero cheCelsius, ingoyeuka 0 ^o C = 32 ^o F uye 100 ^o C = 212 ^o F. Pachikero cheCelsius, pakati pe0 ^o C kusvika 100 ^o C pane 100 ^o . Pachikero cheFahrenheit, pakati pe32 ^o F kusvika 212 ^o F pane 180 ^o.

Kushandura chikero cheCelsius kuita chikero cheFahrenheit

Kuti uwane tembiricha muchikamu cheFahrenheit (T)_F), tanga wawedzera tembiricha muCelsius scale (T)_C) ne9/5 wobva wawedzera pa32^o.

Muenzaniso wemubvunzo 1. 40 ^o C = …. ^o F

Kushandura chikero cheFahrenheit kuita chikero cheCelsius

Kuti uwane tembiricha muCelsius scale (T)_C), kuderedza tembiricha muFahrenheit scale (T_F) ne32^o, wobva wawedzera ne5/9.

Muenzaniso wemubvunzo 2. 60 ^o F = …. ^o C

Muenzaniso wemubvunzo 3. 80 ^o F = …. K

Tarisa mufananidzo unotevera wekuyera tembiricha yechinwiwa uchishandisa thermometer yeFahrenheit! Kana tikayera tembiricha yechinwiwa tichishandisa thermometer yeCelsius, inoratidza tembiricha ye...

A. 20 ^oC
B. 25 ^oC
C. 45 ^oC
D. 98 ^oC

Kukurukurirana

Ubah suhu mukati Chikero cheFahrenheit kusvika paCelsius scale.
T_C = 100/180 (T)_F - 32)
T_C = 5/9 (77 – 32) = 5/9 (45) = 5(5) = 25 ^oC
Mhinduro chaiyo ndeiyi B.

Tembiricha iri mune imwe yemakamuri ekudzidzira i28 ^o C. Kana tembiricha ikayerwa nethermometer yeFahrenheit, inoratidza tembiricha ye…

A. 26,8 ^oF
B. 35,4 ^oF
C. 62,8 ^oF
D. 82,4 ^oF

Kukurukurirana
Kuchinja tembiricha kubva kuCelsius kuenda kuFahrenheit.
T_F = 180/100 T_C + 32
T_F = 9/5 (28) + 32 = 9(5,6) + 32
T_F = 50,4 + 32 = 82,4 ^oF

Mufananidzo unotevera unoratidza tembiricha yemvura yakayerwa uchishandisa thermometer yeCelsius. Dai tembiricha yemvura yakayerwa uchishandisa thermometer yeFahrenheit, tembiricha yemvura yaizova…
A. 40 ^oF
B. 58 ^oF
C. 104 ^oF
D. 122 ^oF
Kukurukurirana
Chinja tembiricha muchikamu cheCelsius kuita chikamu cheFahrenheit.
T_F = 180/100 T_C + 32
T_F = 9/5 (40) + 32 = 9(8) + 32
T_F = 72 + 32 = 104 ^oF
Mhinduro chaiyo ndiC.
