pāʻoihana

Ma ke kaomi lewa maʻamau , ʻo ke kiko hau o ka wai he 0 ^° C ma ka pālākiō Celsius a me 32 ^° F ma ka pālākiō Fahrenheit. Ma ke kaomi lewa maʻamau, ʻo ke kiko paila o ka wai he 100 ^° C ma ka pālākiō Celsius a me 212 ^° F ma ka pālākiō Fahrenheit.

0 ^o C = 32 ^o F a me 1 00 ^o C = 212 ^o F. ʻO kahi loli o 5 C ^o = kahi loli o 9 F ^o.

No ka unahi Celsius, ua māhele ʻia ka mamao ma waena o 0 ^° C a me 100 ^° C i 100 mau wā like. No ka unahi Fahrenheit, ua māhele ʻia ka mamao ma waena o 0 ^° C a me 100 ^° C i 180 mau wā like.

Iā ^F = (180/100) Iā ^C + 32

Iā ^F = (9/5) Iā ^C + 32

Iā ^F = (9/5) 50 + 32

Iā ^F = (9) 10 + 32

Iā F = 90 ⁺ 32

Iā ^F = 122

50 ^o C = 122 ^o F

2. 86 ^o F = ….. ^o C ?

pāʻoihana

Iā ^C = (100/180)(Iā ^F – 32)

Iā ^C = (5/9)(Iā ^F – 32)

Iā ^C = (5/9)(86 – 32)

Iā ^C = (5/9)(54)

Iā ^C = (5)(6)

Iā ^C = 30

86 ^o F = 30 ^o C

3. 50 ^o C = ….. K ?

pāʻoihana

T = Iā ^C + 273

T = 50 + 273

T = 323

50 ^o C = 323 K

ʻAʻole maopopo

4. 212 ^o F = ….. K ?

pāʻoihana

Iā ^C = (100/180)(Iā ^F – 32)

Iā ^C = (5/9)(Iā ^F – 32)

Iā ^C = (5/9)(212 – 32)

Iā ^C = (5/9)(180)

Iā ^C = (5)(20)

Iā ^C = 100

212 ^o F = 100 ^o C + 273

212 ^o F = 373 K

 

5. x ^o C = x ^o F

Hiki ke kākau ʻia ka hoʻololi ʻana ma waena o nā unahi mahana ʻelua:

T _C = 5/9 (T _F – 32)

T _C = Mahana ma Celsius, T _F = mahana ma Fahrenheit

Ka mahana ma Celsius:

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

T _C = 50 ^o C

7. Hōʻike ke kiʻi ma lalo nei i ke ana ʻana o ka mahana o kahi wai me ka ana wela Fahrenheit! Inā ana ʻia ka mahana o ka wai me ka hoʻohana ʻana i ka ana wela Celsius, a laila he aha ka mahana o ka wai e.

ʻIke ʻia:

ʻO ka unahi Fahrenheit (T _F ) = 95 ^o F

Makemake ʻia: Pālākiō Celsius

Lōlā:

Ma ke kaomi o 1 atm, ʻo ke kiko hau o ka wai he 0 °C ʻoiai ʻo ka unahi Fahrenheit he 32 ^° F. I ka ʻaoʻao ʻē aʻe, ʻo ke kiko paila o ka wai no ka unahi Celsius he 100 ^° C ʻoiai ʻo ka unahi Fahrenheit he 212 ^° F.

Ma ke ana wela o Celsius, ma waena o 0 °C a me 100 °C he 100 °, a ma ke ana wela o Fahrenheit mai 32 °F a i 212 °F he 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 ^o C

8. Ma muli o ke kiʻi ma lalo nei, e hoʻoholo i ka mahana P ma ka ana wela Celsius.

pāʻoihana

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 ^o C

9. Inā like ka mahana o ke anakahi Celsius me ka mea i hōʻike ʻia ma ke kiʻi ma lalo, e hoʻoholo i ka mahana o ke anakahi Fahrenheit e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo.

Lōlā:

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

Iā ^F = (9/5) Iā ^C + 32

Iā ^F = (9/5) 60 + 32

Iā ^F = (9) 12 + 32

Iā F = 108 ⁺ 32

Iā ^F = 140
