Ka hoʻololi ʻana i nā ʻāpana kaomi kinoea

ʻO ke kaomi kinoea ke kaomi o ka paia hāʻawi kinoea, ʻo ia ka hōʻike macroscopic o ka nui o nā molekala e hoʻomau mau ana i ka pā a he ʻāpana koʻikoʻi i hoʻohana ʻia e wehewehe i ke kūlana o ka ʻōnaehana. ʻO ka nui o nā waiwai kino a me nā kemika, e like me ke kiko, ka paila, ka mahu, ʻaneʻane pili i ke kaomi. He mea koʻikoʻi ke kaomi i ke aʻo ʻana i nā thermodynamics kemika a me nā kinetics kemika. No laila, he mea nui ke ana o ke kaomi.

ʻO nā ʻāpana maʻamau: bar (bar), pascal (Pa). ʻO kahi ʻāpana o ke kaomi, ma ka physics, pili i ka ikaika e hana kū pololei ana ma ka ʻili o kahi mea. ʻO Pascal ka ʻāpana (i hoʻopau ʻia ʻo Pa ʻO ka leka ʻo "Pa"). (ʻO ka ʻōlelo koʻikoʻi, ʻo Newton N ka ʻāpana kaomi. ”), ʻo ka wae “kg•f/cm2″, he kilokani o ke kaomi he kilokani o ka ikaika e hana ana ma ke kenimika huinaha.

1 Pumi lewa maʻamau = 760mmHg = 76cmHg = 1.01325×105Pa=10.336m kolamu wai. 1 kaomi lewa maʻamau

= 101325 N/㎡. (Maʻamau 1 lewa maʻamau = 1.01×105Pa i ka helu ʻana)

Inā makemake ʻoe e helu pololei, penei ka pilina:

ʻO ka pilina hoʻololi kaomi:

1 dyne no ke kenimika huinaha (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa

1 milimita o ka mercury (mmHg) = 133.322 Pa (Pa)
