Te tahuritanga pāmahana

He rerekē ngā tauine pāmahana o te Celsius me te Fahrenheit. Mēnā ka inehia te pāmahana o tētahi mea, ā, ka whakaaturia ki te Celsius, ā, e hiahia ana tātou ki te whakaatu i te pāmahana ki te Fahrenheit, ka hurihia e tātou mai i te Celsius ki te Fahrenheit. I tēnei wāhanga, ka ako tātou me pēhea te huri, te mahi rānei te hurihanga pāmahana.

I te pēhanga o te 1 atm, ko te pāmahana hukapapa mō te inemahana Celsius = 0 ^oC, ko te tauine o te inemahana Fahrenheit he 32 ^oF. I tetahi atu taha, i te pēhanga o te 1 atm, ko te pāmahana pūwāhi kohu mō te inemahana tauine Celsius = 100 ^oC, ko te tauine o te inemahana Fahrenheit he 212 ^oMātakitakihia te pikitia i raro nei!

Hei whakangāwari ake i te huri i te tauine Celsius ki te tauine Fahrenheit, te huri rānei i te tauine Fahrenheit ki te tauine Celsius, kia maumahara noa ki te 0. ^oC=32 ^oF me te 100 ^oC=212 ^oF. I te tauine Celsius, i waenganui i te 0 ^oC ki te 100 ^oKei roto i te C te 100^oI runga i te tauine Fahrenheit, i waenganui i te 32 ^oF ki te 212 ^oKei roto i te F te 180^o.

Te huri i te tauine Celsius ki te tauine Fahrenheit

Hei whiwhi i te pāmahana i te tauine Fahrenheit (T_F), whakareatia te pāmahana ki te tauine Celsius (T_C) me te 9/5 kātahi ka tāpirihia ki te 32^o.

Te huri i te tauine Fahrenheit ki te tauine Celsius

Hei whiwhi i te pāmahana i te tauine Celsius (T_C), whakaitihia te pāmahana i te tauine Fahrenheit (T_F) me te 32^o, kātahi ka whakareatia ki te 5/9.

Tirohia te whakaahua e whai ake nei o te ine pāmahana o tētahi wai mā te whakamahi i te inemahana Fahrenheit! Ki te ine tātou i te pāmahana o te wai mā te whakamahi i te inemahana Celsius, ka whakaatuhia he pāmahana o...

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

Kōrero

Ubah te pāmahana i roto Tauine Fahrenheit ki te tauine Celsius.
T_C = 100/180 (T_F - 32)
T_C = 5/9 (77 – 32) = 5/9 (45) = 5(5) = 25 ^oC
Ko te whakautu tika ko B.

Ko te pāmahana i roto i tētahi o ngā akomanga he 28 ^oC. Ki te inehia te pāmahana ki te inemahana Fahrenheit, ka whakaatuhia he pāmahana o…

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

Kōrero
Te huri i te pāmahana mai i Celsius ki 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
Ko te whakautu tika ko D.

E whakaatu ana te pikitia e whai ake nei i te pāmahana o tētahi wai i inehia mā te whakamahi i te inemahana Celsius. Mēnā ka inehia te pāmahana o te wai mā te whakamahi i te inemahana Fahrenheit, ko te pāmahana o te wai ko…
A. 40 ^oF
B. 58 ^oF
C. 104 ^oF
D. 122 ^oF
Kōrero
Tahurihia te pāmahana i te tauine Celsius ki te tauine Fahrenheit.
T_F = 180/100 T_C + 32
T_F = 9/5 (40) + 32 = 9(8) + 32
T_F = 72 + 32 = 104 ^oF
Ko te whakautu tika ko C.
