Sama sem razmišljala nekak v smeri, da je v svežem zraku več o2 in manj co2. Ker je (molska?) masa o2<co2, je verjetno treba manj E, da za isto spremembo T segreješ isto prostornino..... ??
bi lahko mogoče kdo s kako enačbico postregel?!

em, zanima me, če je moje opažanje, da se prezračena soba bolj ogreje(ko se ogreje), kot če maš notri "slab zrak", pravilno. Oziroma, če se ga da kako znanstveno podpreti.
