Nā ʻAno Unahi Ana wela

I mea e hoʻohana ʻia ai kahi ana wela e ana i ka mahana, pono e wehewehe ʻia ma kahi unahi. ʻElua mau unahi ana wela i hoʻohana pinepine ʻia , ʻo ia ka unahi Celsius a me ka unahi Fahrenheit. ʻO ka unahi mahana i hoʻohana nui ʻia ma Indonesia, ʻo ia ka unahi Celsius. ʻO kekahi inoa no ka unahi Celsius, ʻo ia ka unahi centigrade. Centigrade = hoʻokahi haneli ʻanuʻu. Hoʻohana pinepine ʻia ka unahi Fahrenheit ma ʻAmelika Hui Pū ʻIa a i ʻole nā ​​ʻāina me nā hoʻoilo anuanu. ʻO kahi unahi mahana koʻikoʻi i ka ʻepekema, ʻo ia ka unahi paʻa, a i ʻole ka unahi Kelvin. E kūkākūkā ʻia ka unahi Kelvin ma hope.

Hoʻohana nā unahi Celsius a me Fahrenheit i nā kiko hau a me nā kiko paila o ka wai ma ke ʻano he mau kiko paʻa. ʻO ke kiko hau o kahi mea ka mahana ma kahi o nā pae paʻa a me nā pae wai i ke kaulike wela . I ka ʻaoʻao ʻē aʻe, ʻo ke kiko paila o kahi mea ka mahana ma kahi o nā pae wai a me nā pae kinoea i ke kaulike wela. Hoʻololi mau nā kiko hau a me nā kiko paila me ke kaomi ea, no laila pono e hoʻoholo mua ʻia ke kaomi ea. Hoʻohana pinepine mākou i ke kaomi maʻamau, ʻo ia hoʻi 1 atm (hoʻokahi lewa). ʻO ka lewa kahi anakahi o ke kaomi ea.

ʻO ke kiko paʻa o luna o ke anakahi Celsius e hoʻohana ana i ke kiko paila o ka wai maʻemaʻe, ʻoiai ʻo ke kiko paʻa haʻahaʻa o ke anakahi Celsius e hoʻohana ana i ke kiko hau o ka wai maʻemaʻe. ʻO ke kiko hau o ka wai maʻemaʻe (i kapa ʻia hoʻi he kiko hau) he ʻole kekelē Celsius (0 ^° C), a ʻo ke kiko paila o ka wai maʻemaʻe (i kapa ʻia hoʻi he kiko mahu) he hoʻokahi haneli kekelē Celsius (100 ^° C). Ma waena o ke kiko hau a me ke kiko mahu he 100 kekelē. Ma nā ana wela e hoʻohana ana i ke anakahi Celsius, ʻo nā mahana haʻahaʻa ma mua o ke kiko hau e hōʻailona pinepine ʻia me nā helu maikaʻi ʻole.

Pālākiō Fahrenheit

Ua makemake ʻo Fahrenheit i nā unahi mahana a pau e maikaʻi. No laila, ua koho ʻo ia i 0 ^° F no ka mahana o ka hui ʻana o ka hau a me ka wai paʻakai (hiki i ka wai ke anuanu loa ke hiki). I ke ana ʻana i nā mahana o ka hau a me ke kiko mahu, ʻo nā helu i hōʻike ʻia ma ka unahi Fahrenheit he mau hapa. I ka hopena, ua hoʻololi ʻo ia i ka unahi i mea e lilo ai nā mahana o ka hau a me ke kiko mahu i mau helu holoʻokoʻa.

No ke anakahi Fahrenheit, ʻo ke kiko hau o ka wai maʻemaʻe (kiko hau) he 32 degere Fahrenheit (32 ^o F) a ʻo ke kiko paila o ka wai maʻemaʻe (kiko mahu) he 212 degere Fahrenheit (212 ^o F). Ma waena o ke kiko hau a me ke kiko mahu he 180 degere. ʻO ka wai maʻemaʻe ka wai i hui ʻole ʻia me nā mea ʻē aʻe. H ₂ 0 maʻemaʻe.

Ke ʻōlelo mākou i kahi mahana, a laila kapa mākou ia kekelē Kelekia (^oC) a i ʻole kekelē Fahrenheit (^oF). Laʻana: ka mahana o ka wai wela = 100 ^oC a i ʻole 180 ^oF. ʻO ka mahana o koʻu kino = 98 ^oF. Ma ka ʻaoʻao ʻē aʻe, inā mākou e ʻōlelo i kahi loli o ka mahana a i ʻole kahi ʻokoʻa o ka mahana, a laila kapa mākou ia Nā kekelē Celsius (C^o) a i ʻole Nā kekelē Fahrenheit (F^o). Laʻana: ʻo ka mahana mua o ka wai he 20 ^oC. Ma hope o ka hoʻomehana ʻia ʻana, loli ka mahana i 50 ^oC. No laila, ʻike ka wai i kahi loli mahana o 30 Nā kekelē Celsius (30 kekelē Celsius)^o).
