Tus nqi ntawm cov dej vapor nyob rau hauv huab cua Nws txawv ntawm 0-4% nyob ntawm qhov kub thiab txias, siab thiab qhov chaw.

Yog li ntawd, dab tsi yog txhais los ntawm lub xeev gaseous?

gaseous xeev - tus xeev ntawm cov teeb meem txawv ntawm cov khoom thiab cov kua xeev los ntawm: tsawg ntom thiab viscosity; kuj zoo heev expansion thiab contraction nrog kev hloov nyob rau hauv siab thiab kub; muaj peev xwm diffuse yooj yim; thiab qhov kev xav tsis zoo los ua kev faib tawm ib yam thoob plaws ib qho

Ib yam li ntawd, roj thiab nws cov khoom yog dab tsi? Roj muaj peb yam ntxwv khoom : (1) lawv yooj yim rau compress, (2) lawv nthuav mus sau lawv ntim, thiab (3) lawv nyob deb tshaj qhov chaw tus kua los yog cov khoom uas lawv tsim. Compressibility. Internal combustion engine muab ib tug piv txwv zoo ntawm tus yooj yim nrog uas cov pa tuaj yeem compressed.

Tom qab ntawd, lo lus nug yog, dab tsi yog lub xeev gaseous?
