He tauira o ngā pātai mō te hurihanga o ngā waeine pāmahana

5 Tauira o ngā Raru Hurihanga Wāhanga Mahana

1. Ko te pāmahana o tētahi mea he 122°F, ina inehia ki te tauine Celsius, ko...

A. 323°C

B. 122°C

C. 50°C

D. 40°C

Kōrero

Te tātai whakawhiti pāmahana mai i Fahrenheit ki Celsius:

T _C = 5/9 (T _F – 32)

Whakaahuatanga: T _C = te pāmahana i te tauine Celsius, T _F = te pāmahana i te tauine Fahrenheit

Ko te pāmahana i te tauine Celsius ko:

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

T _C = 50 ^o C

Ko te whakautu tika ko C.

2. He kirika tō te tamaiti, ina inehia ki te inemahana he rua ōna tauine, ko te tau e whakaaturia ana i te tauine Celsius ko te 40°, kātahi ko te tau e whakaaturia ana i te tauine Reamur ko...

A. 31 °R

B. 32 °R

C. 45 °R

D. 50°R

Kōrero

E mōhiotia ana:

Te pāmahana i te tauine Celsius (T ^o C) = 40

Pātai: Te pāmahana i te tauine Reamur (T ^o R )

Whakautu:

Te pāmahana kohua o te wai parakore (H ₂ O) = 100 ^o C = 80 ^o R

Te pāmahana tio o te wai parakore (H ₂ O) = 0 ^o C = 0 ^o R

Tauine hurihanga Celsius ki Reamur:

T ^o R = (80/100) T ^o C

T ^o R = (4/5) T ^o C

Ki ^R ​​= (4/5) 40

T ^o R = (4)(8)

T ^o R = 32 ^o R

Ko te whakautu tika ko B.

3. Tirohia te ahua o te inemahana kei te taha! Ko te pāmahana Y i runga i te tauine inemahana Celsius ko…

A. 172 ^oC
B. 108 ^oC
C. 60 ^oC
D. 44 ^oC

Kōrero

E mōhiotia ana:
Tauine Fahrenheit = 140 ^oF
I pātaihia: Tauine Celsius
Whakautu:

Ko te tātai mō te huri i te tauine Fahrenheit ki te tauine Celsius:
T ^oC = 5/9 (T ^oF – 32)
Tauine Celsius:
T ^oC = 5/9 (140 – 32)
T ^oC = 5/9 (108)
T ^oC = 540/9
T ^oC=60
Ko te whakautu tika ko C.

4.

Kia tūpato ki ngā inenga pāmahana e whai ake nei! Ko te uara Y i runga i te inemahana Fahrenheit ko…

A. 54 ^oF
B. 65 ^oF
C. 76 ^oF
D. 86 ^oF

Kōrero
E mōhiotia ana:
Tauine Celsius = 30 ^oC
I pātaihia: Tauine Fahrenheit
Whakautu:
Ko te tātai mō te huri i te tauine Celsius ki te tauine Fahrenheit:
T ^oF = (9/5)(T ^oC) + 32
Tauine Fahrenheit:
T ^oF = (9/5)(30) + 32
T ^oF = (270/5) + 32
T ^oF = 54 + 32
T ^oF = 86
Ko te whakautu tika ko D.

5. Tirohia te pikitia ine pāmahana e whai ake nei! E whakaatu ana te inemahana Fahrenheit i te pāmahana….
A. 92 ^oF
B. 108 ^oF
C. 122 ^oF
D. 140 ^oF
Kōrero
E mōhiotia ana:
Tauine Celsius = 60 ^oC
I pātaihia: Tauine Fahrenheit
Whakautu:
Ko te tātai mō te huri i te tauine Celsius ki te tauine Fahrenheit:
T ^oF = (9/5)(T ^oC) + 32
Tauine Fahrenheit:
T ^oF = (9/5)(60) + 32
T ^oF = (9)(12) + 32
T ^oF = 108 + 32
T ^oF = 140
Ko te whakautu tika ko D.
