Gli atomi o le molecole del gas sono liberi di muoversi assumendo ciascuno una certa velocità: le particelle atomiche o molecolari del gas quindi interagiscono urtandosi continuamente l'un l'altra. Per questo un gas non ha un volume definito ma tende a occupare tutto lo spazio a sua disposizione, e assume la forma del contenitore che lo contiene, riempiendolo. Un altro vincolo che può limitare il volume di un gas è un <a href="https://it-m-wikipedia-org.translate.goog/wiki/Campo_gravitazionale?_x_tr_sl=auto&amp;_x_tr_tl=en&amp;_x_tr_hl=en-GB" title="Campo gravitazionale">campo gravitazionale</a>, come nel caso dell'<a href="https://it-m-wikipedia-org.translate.goog/wiki/Atmosfera?_x_tr_sl=auto&amp;_x_tr_tl=en&amp;_x_tr_hl=en-GB" title="Atmosfera">atmosfera terrestre</a>.</p> <p>Nel linguaggio corrente si dice che una data sostanza "è un gas" quando la sua <a href="https://it-m-wikipedia-org.translate.goog/wiki/Temperatura_di_ebollizione?_x_tr_sl=auto&amp;_x_tr_tl=en&amp;_x_tr_hl=en-GB" class="mw-redirect" title="Temperatura di ebollizione">temperatura di ebollizione</a> è molto al di sotto della temperatura ambiente, cioè quando si trova normalmente allo stato di gas sulla <a href="https://it-m-wikipedia-org.translate.goog/wiki/Terra?_x_tr_sl=auto&amp;_x_tr_tl=en&amp;_x_tr_hl=en-GB" title="Terra">Terra</a>.
