Ukuguqulwa kwezinga lokushisa

Izikali ze-Celsius ne-Fahrenheit ziyizilinganiso zokushisa ezihlukile. Uma izinga lokushisa lento lilinganiswa futhi livezwa nge-Celsius bese sifuna ukuveza izinga lokushisa lento nge-Fahrenheit, siguqula kusuka ku-Celsius kuya ku-Fahrenheit. Kulesi sigaba, sifunda ukuthi singaguqula kanjani noma senze kanjani izinguquko zokushisa.

Uma ingcindezi ingu-1 atm, izinga lokushisa leqhwa le-thermometer ye-Celsius = 0 ^oC, kuyilapho isikali se-thermometer se-Fahrenheit = 32 ^oF. Ngakolunye uhlangothi, ekucindezelweni okungu-1 atm, izinga lokushisa lephuzu lomhwamuko le-thermometer yesikali se-Celsius = 100 ^oC, kuyilapho isikali se-thermometer se-Fahrenheit = 212 ^oF. Bheka isithombe esingezansi!

Ukuze kube lula ngawe ukuguqula isikali se-Celsius sibe yi-Fahrenheit noma ukuguqula isikali se-Fahrenheit sibe yi-Celsius, khumbula nje ukuthi u-0 ^o C = 32 ^o F kanye no-100 ^o C = 212 ^o F. Esikalini se-Celsius, phakathi kuka-0 ^o C no-100 ^o C kukhona u-100 ^o . Ngenkathi esikalini se-Fahrenheit, phakathi kuka-32 ^o F no-212 ^o F kukhona u-180 ^o.

Ukuguqula isikali se-Celsius sibe isikali se-Fahrenheit

Ukuze uthole izinga lokushisa esikalini se-Fahrenheit (T)_F), qala ngokuphindaphinda izinga lokushisa esikalini se-Celsius (T)_C) nge-9/5 bese uyifaka ku-32^o.

Isibonelo sombuzo 1. 40 ^o C = …. ^o F

Ukuguqula isikali se-Fahrenheit sibe isikali se-Celsius

Ukuthola izinga lokushisa ngesikali se-Celsius (T)_C), nciphisa izinga lokushisa esikalini se-Fahrenheit (T_F) kanye no-32^o, bese uphindaphinda ngo-5/9.

Bheka isithombe esilandelayo sokulinganisa izinga lokushisa koketshezi kusetshenziswa i-thermometer ye-Fahrenheit! Uma silinganisa izinga lokushisa koketshezi sisebenzisa i-thermometer ye-Celsius, kuzobonisa izinga lokushisa...

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

Ubah shu phakathi Isikali se-Fahrenheit kuya esikalini seCelsius.
T_C = 100/180 (T_F - 32)
T_C = 5/9 (77 – 32) = 5/9 (45) = 5(5) = 25 ^oC
Impendulo efanele ingu-B.

Ukuguqula izinga lokushisa kusuka ku-Celsius kuya ku-Fahrenheit.
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
Impendulo efanele ngu-D.

Guqula izinga lokushisa esikalini se-Celsius libe isikali se-Fahrenheit.
T_F = 180/100 T_C 32 +
T_F = 9/5 (40) + 32 = 9(8) + 32
T_F = 72 + 32 = 104 ^oF
Impendulo efanele ngu-C.
