9 Izikali zokushisa eziguqulayo (isikali se-Celsius isikali se-Fahrenheit isikali se-Kelvin)

1. 50 ^oC = ….. ^oF ?

Isixazululo

Esimweni esijwayelekile somoya ingcindezi, iphuzu lokubanda kwamanzi lingu-0 ^oC ku- Isikali se-Celsius futhi 32 ^oF esikalini se-Fahrenheit. Uma ucindezela umoya ojwayelekile, izinga lokubila kwamanzi lingu-100 ^oU-C esikalini se-Celsius kanye no-212 ^oF esikalini se-Fahrenheit.

0 ^oC=32 ^oF kanye no-100 ^oC=212 ^oF. Ushintsho lwe-5 C^o = ushintsho lwe-9 F^o.

Ngesilinganiso se-Celsius, ibanga eliphakathi 0 ^oC no-100 ^oI-C ihlukaniswe ngezikhawu eziyi-100 ezilinganayo. Ngesilinganiso se-Fahrenheit, ibanga eliphakathi kuka-0 ^oC no-100 ^oI-C ihlukaniswe ngezikhawu ezilinganayo eziyi-180.

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

50 ^oC=122 ^oF

2. 86 ^oF = ….. ^oC ?

Isixazululo

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 ^oF=30 ^oC

3. 50^oC = ….. K ?

Isixazululo

T = T ^oC + 273

T = 50 + 273

T = 323

50 ^oC= I-323 K

4. 212^oF = ….. K ?

Isixazululo

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 ^oF=100 ^oC + 273

212 ^oF=373 K

 

5.x ^oC = x ^oF

x = ….. ?

Isixazululo

1: Ukuguqula isikali se-Celsius sibe isikali se-Fahrenheit

2: Ukuguqula isikali se-Fahrenheit sibe isikali se-Celsius

6. 122°F = ….. Celsius

Isixazululo

Ukuguqulwa phakathi kwezikali ezimbili zokushisa kungabhalwa kanje:

T_C = 5/9 (T_F - 32)

T_C = Temperature ngo-Celsius, T_F = izinga lokushisa ku-Fahrenheit

Izinga lokushisa ngama-Celsius:

T_C = 5/9 (122 – 32) = T_C = 5/9 (90) = 5 (10)

T_C = 50 ^oC

7. Isithombe esingezansi sibonisa ukulinganisa izinga lokushisa kwe a uketshezi olusebenzisa i-thermometer yesikali se-Fahrenheit! Uma izinga lokushisa loketshezi lilinganiswa kusetshenziswa i-thermometer yesikali se-Celsius, khona-ke kuyini izinga lokushisa loketshezie.

Kwaziwa:

Fahrenheit isikali (T_F= = 95^oF

Kufunwa: Isikali se-Celsius

Isixazululo:

Uma ucindezelekile nge-atm eyi-1, iphuzu lokuqandisa kwamanzi is 0 °C kuyilapho isikali se-Fahrenheit singama-32 ^oF. Ngokuphambene nalokho, tiphuzu lokubila kwamanzi ye-CU-Elsius isikali siyi-100 ^oC ngenkathi isikali se-Fahrenheit is 212 ^oF.

Esikalini se-Celsius, phakathi kuka-0 °C no-100 °C kukhona i-100 ° kanti esikalini se-Fahrenheit esiphakathi kuka-32 °F no-212 °F kukhona i-180 °.

T_C = 100/180 (T_F - 32)

T_C = 5/9 (T_F - 32)

T_C = 5/9 (95 - 32)

T_C = 5/9 (63)

T_C = 315 / 9

T_C = 35^oC

8. Ngokusekelwe esithombeni esingezansi, nquma u-tizinga lokushisa P ku-thermometer ye-Celsius.

Isixazululo

T_C = 100/180 (T_F - 32)

T_C = 5/9 (T_F - 32)

T_C = 5/9 (104 – 32)

T_C = 5/9 (72)

T_C = 360 / 9

T_C = 40 ^oC

9. Uma izinga lokushisa lesilinganiso se-Celsius njengoba kuboniswe esithombeni esingezansi, thola izinga lokushisa lesilinganiso se-Fahrenheit njengoba kuboniswe esithombeni esingezansi.

Isixazululo:

T^oF = (180/100) T^oC + 32

T^oF = (9/5) T^oC + 32

T^oF = (9/5) 60 + 32

T^oF = (9) 12 32 +

T^oF=108 32 +

T^oF=140
