Thomas Andrews

Died 26 Nov 1885 at age 71 (born 19 Dec 1813). Irish physical chemist who demonstrated the continuity of the gaseous and liquid states whereby during changes between the two states, physical properties display no abrupt changes. He discovered the critical temperature for carbon dioxide (1861), above which the gas cannot be liquefied by pressure alone. He wrote: We may yet live to see...such bodies as oxygen and hydrogen in the liquid, perhaps even in the solid state. He accurately measured heats of neutralisation, formation and reaction; and latent heats of evaporation. Andrews was the first to use a "bomb calorimeter" - a strong, sealed, metal vessel for measuring heat of combustion. He studied ozone, and proved that is an allotrope - or altered form - of oxygen.«
