Canza raka'a matsa lamba gas

Matsin iskar gas shine matsa lamba na bangon mai ba da iskar gas, wanda shine bayyanar macroscopic na adadi mai yawa na kwayoyin da ke ci gaba da tasiri ga bangon kuma muhimmin ma'auni ne da ake amfani da shi don kwatanta yanayin tsarin. Yawancin abubuwa na zahiri da na sinadarai, kamar aya, wurin tafasa, matsa lamba, kusan duk sun dogara da matsa lamba. Har ila yau, matsa lamba abu ne mai mahimmanci a cikin nazarin ilimin thermodynamics da sinadaran kinetics. Saboda haka, ma'aunin matsi yana da mahimmanci.

Raka'o'in da aka fi amfani da su sune: mashaya (bar), pascal (Pa). Ƙungiyar matsa lamba, a ilimin lissafi, tana nufin ƙarfin aiki a tsaye a saman wani abu. Naúrar ita ce Pascal (wanda aka taƙaita a matsayin Pa Harafin "Pa"). (Madaidaicin magana, naúrar matsa lamba ya kamata ya zama Newton N.) Naúrar matsin lamba shine Pascal, kuma al'ada ce a kira matsin lamba a rayuwa) A kasar Sin, gabaɗaya mun kwatanta matsi na iskar gas a matsayin "kilogram" (ba "jin" ba. ”), sashin “kg•f/cm2″, kilogiram na matsa lamba shine kilogiram na karfi da ke aiki akan santimita murabba'i.

1Standard atmospheric matsa lamba = 760mmHg = 76cmHg = 1.01325 × 105Pa = 10.336m ruwa shafi. 1 daidaitaccen matsi na yanayi

= 101325 N/㎡. (Yawanci 1 daidaitaccen yanayi = 1.01 × 105Pa a lissafin)

Idan kuna son yin ainihin lissafi, dangantakar ita ce kamar haka:

Alakar canza matsi:

1 dyne a kowace santimita murabba'in (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa
