+Tlak v plinu je odvisen od prostornine plina, njegove temperature in mase
+ plina.
+ Če opazujemo ves čas isto maso plina in poskrbimo, da je ena od preostalih
+ spremenljivk konstantna, lahko ugotovimo medsebojno odvisnost še zadnjih
+ dveh spremenljivk.

+\begin_inset Formula $\sigma$
+\end_inset
+
+ je precej majhna, torej so podatki zelo točni, niso pa natančni, od dejanske
+ absolutne ničle občutno odstopajo.
+ To pa zato, ker je bilo za dosego večje točnosti izvedenih 655 meritev,
+ med vsako meritvo pa je pretekla le ena sekunda.
+ Graf je zato zamaknjen, saj se plin ni v celoti ogrel na temperaturo vode,
+ termometer pa je bil v vodi, ki se je segrela prej kot plin.
+ S čakanjem na ustaljenost temperature bi težavo natančnosti za ceno manjše
+ točnosti odpravili.
