Standard Zomwe zimatchulidwa ndizofunikira pakuwonetsa kuchuluka kwa madzimadzi komanso kuchuluka kwa zakumwa ndi mpweya, zomwe zimadalira kwambiri kutentha ndi kupanikizika. STP imagwiritsidwa ntchito nthawi zambiri muyezo zikhalidwe za boma zimagwiritsidwa ntchito powerengera.

Komanso dziwani, tanthauzo la kutentha ndi kupanikizika kumatanthauza chiyani?

Kutentha kokhazikika ndi kuthamanga, chidule cha STP, chimatanthawuza mikhalidwe yodziwika bwino mumlengalenga pamlingo wanyanja. Kutentha koyenera ndi kufotokozedwa ngati zero digiri Celsius (0 0C), kumasulira kwa madigiri 32 Fahrenheit (32 0F) kapena 273.15 madigiri kelvin (273.15 0K).

Kachiwiri, kodi standard pressure imatanthauza chiyani? kukakamizidwa muyezo -gawo la kupanikizika: ndi kupanikizika zomwe zimathandizira ndime ya mercury 760 mm m'mwamba pamtunda wa nyanja ndi madigiri 0 centigrade. atm, muyezo mpweya, mpweya. kupanikizika unit - mphamvu yoyezera mayunitsi pagawo lililonse. s.t.p., STP - muyezo kutentha ndi kupanikizika.

Apa, pali kusiyana kotani pakati pa STP ndi mikhalidwe yokhazikika?

Mtengo wa STP ndi lalifupi za Standard Kutentha ndi Kupanikizika, komwe kumatanthauzidwa kukhala 273 K (0 madigiri Celsius) ndi 1 atm pressure (kapena 10).5 Pa). Mtengo wa STP akufotokoza zinthu muyezo ndipo amagwiritsidwa ntchito nthawi zambiri za kuyeza kuchuluka kwa gasi ndi kuchuluka kwake pogwiritsa ntchito Ideal Gas Law. The boma lokhazikika kutentha ndi 25 degrees C (298 K).

Mukutanthauza chiyani ponena za pressure?

Kupanikizika amatanthauzidwa ngati mphamvu yakuthupi yogwiritsidwa ntchito pa chinthu. Mphamvu yogwiritsidwa ntchito ndi perpendicular pamwamba pa zinthu pa unit dera. Chigawo cha kupanikizika Pascals (Pa).
