:''T''<sup> <s>o</s></sup> היא הטמרפטורה הסטנדרטית (298K).
 
משוואה זו אינה מדויקת, אלא מקורבת בלבד. מומלץ להשתמש בנוסחה מבוססת ניסויים עבור הגז הנתון, שתהיה מדויקת יותר.

Because solubility of gases is decreasing with increasing temperature, the partial pressure a given gas concentration has in liquid must increase. While heating water (saturated with nitrogen) from 25 °C to 95 °C the solubility will decrease to about 43% of its initial value. This can be verified when heating water in a pot: small bubbles evolve and rise, long before the water reaches boiling temperature. Similarly, carbon dioxide from a [[Carbonation|carbonated]] drink escapes much faster when the drink is not cooled because of the increased partial pressure of CO<sub>2</sub> in higher temperatures. Partial pressure of CO<sub>2</sub> in seawater doubles with every 16 K increase in temperature.<ref>Takahashi, T; Sutherland, SC; Sweeney, C; Poisson, A; Metzl, N; Tilbrook, B; Bates, N; Wanninkhof, R; Feely, RA; Sabine, C; Olafsson, J; Nojiri, Y "''Global sea-air CO<sub>2</sub> flux based on climatological surface ocean pCO<sub>2</sub> and seasonal biological and temperature effects''" Deep-Sea Research (Part II, Topical Studies in Oceanography) [Deep-Sea Research (II Top.
