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

1. 50 ^o C = ….. ^o F ?

Isixazululo

Uma kuqhathaniswa nengcindezi yomoya ejwayelekile , izinga lokuqandisa kwamanzi lingu-0 ^o C esikalini se-Celsius kanye no-32 ^o F esikalini se-Fahrenheit. Uma kuqhathaniswa nengcindezi yomoya ejwayelekile, izinga lokubila kwamanzi lingu-100 ^o C esikalini se-Celsius kanye no-212 ^o F esikalini se-Fahrenheit.

0 ^o C = 32 ^o F kanye no-1 00 ^o C = 212 ^o F. Ushintsho lwe-5 C ^o = ushintsho lwe-9 F ^o.

Ngesilinganiso se-Celsius, ibanga eliphakathi kuka -0 ^o C no-100 ^o C lihlukaniswe ngezikhawu eziyi-100 ezilinganayo. Ngesilinganiso se-Fahrenheit, ibanga eliphakathi kuka-0 ^o C no-100 ^o C lihlukaniswe ngezikhawu eziyi-180 ezilinganayo.

Kuya ^ku- F = (180/100) Kuya ^ku- C + 32

Kuya ^ku- F = (9/5) Kuya ^ku- C + 32

Kuya ^ku- F = (9/5) 50 + 32

Kuya ^ku- F = (9) 10 + 32

Kuze ^{kube ngu-} F = 90 + 32

Kuze ^{kube ngu-} F = 122

50 ^o C = 122 ^o F

2. 86 ^o F = ….. ^o C ?

Isixazululo

Kufika ^ku- C = (100/180)(Kufika ku ^- F – 32)

Kufika ^ku- C = (5/9)(Kufika ku ^- F – 32)

Kufika ^ku- C = (5/9)(86 – 32)

Kufika ^ku- C = (5/9)(54)

Kufika ^ku- C = (5)(6)

Kufika ku ^- C = 30

86 ^o F = 30 ^o C

3. 50 ^o C = ….. K ?

Isixazululo

T = Kuya ku ^- C + 273

T = 50 + 273

T = 323

50 ^o C = 323 K

4. 212 ^o F = ….. K ?

Isixazululo

Kufika ^ku- C = (100/180)(Kufika ku ^- F – 32)

Kufika ^ku- C = (5/9)(Kufika ku ^- F – 32)

Kufika ^ku- C = (5/9)(212 – 32)

Kufika ^ku- C = (5/9)(180)

Kufika ^ku- C = (5)(20)

Kufika ku ^- C = 100

212 ^o F = 100 ^o C + 273

212 ^o F = 373 K

 

5. x ^o C = x ^o F

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:

I-T _C = 5/9 (I-T _F – 32)

T _C = Izinga lokushisa ngo-Celsius, T _F = izinga lokushisa ngo-Fahrenheit

Izinga lokushisa ngama-Celsius:

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

I-T _C = 50 ^o C

7. Isithombe esingezansi sibonisa ukulinganiswa kwezinga lokushisa koketshezi nge-thermometer yesikali se-Fahrenheit! Uma izinga lokushisa koketshezi kulinganiswa kusetshenziswa i-thermometer yesikali se-Celsius, pho liyini izinga lokushisa koketshezi e.

Kwaziwa:

Isikali se- Fahrenheit (T _F ) = 95 ^o F

Okufunwayo: Isikali se-Celsius

Isixazululo:

Uma ingcindezi ingu-1 atm, iphuzu lokubanda lamanzi lingu- 0 °C kanti izinga le-Fahrenheit lingu-32 ^o F. Ngokuphambene nalokho, iphuzu lokubila lamanzi esikalini se -Celsius lingu-100 ^o C kanti izinga le-Fahrenheit lingu- 212 ^o F.

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 °.

I-T _C = 100/180 (I-T _F – 32)

I-T _C = 5/9 (I-T _F – 32)

I-T _C = 5/9 ( 95 – 32)

I-T _C = 5/9 ( 63 )

I-T _C = 315/9

I-T _C = 35 ^o C

8. Ngokusekelwe esithombeni esingezansi, thola izinga lokushisa u-P ku-thermometer ye-Celsius.

Isixazululo

T_C = 100/180 (T_F - 32)

I-T _C = 5/9 (I-T _F – 32)

I-T _C = 5/9 (104 - 32)

I-T _C = 5/9 (72)

I-T _C = 360/9

I-T _C = 40 ^o C

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

Kuya ^ku- F = (9/5) Kuya ^ku- C + 32

Kuya ^ku- F = (9/5) 60 + 32

Kuya ^ku- F = (9) 12 + 32

Kuze ^{kube ngu-} F = 108 + 32

Kuze ^{kube ngu-} F = 140
