Cov kev sib cog lus no muab kev nkag siab rau kev ruaj ntseg ntawm cov tshuaj lom neeg thiab lub zog ntawm cov tshuaj tiv thaiv uas tuav nws cov atoms ua ke.

Daim ntawv cog lus parameter piav qhia nws yog dab tsi?

Zaj. Muaj qee yam tseem ceeb uas cuam tshuam rau cov tshuaj lom neeg ntawm ob lub atom uas yog hu ua daim ntawv cog lus. Daim ntawv cog lus tsis yog: daim ntawv cog lus ntev, daim ntawv cog lus lub kaum ntse ntse, daim ntawv cog lus enthalpy thiab daim ntawv txiav txim. Bond ntev yog qhov kev ncua deb ntawm lub nuclei ntawm cov atoms uas sib koom ua ke.
