Paper, 'On the limit of the liquid state' by J B [James Ballantyne] Hannay

Reference number: PP/1/25

Date: 1881

Description

Hannay writes: 'The uncertainty which characterises our knowledge of the true condition of a fluid immediately above and below the critical temperature, induced me to enter into a full examination of various fluids, with the object of gaining accurate definitions of the liquid and gaseous states, as well as to arrive at a true conception of the state of matter to which the term vapour can be applied. In a former paper, which the Royal Society has honoured me by publishing, experiments were detailed which seemed to show that the liquid state terminated at the critical temperature, and that no amount of pressure would suffice at any higher temperature to render the fluid capable of exhibiting surface tension or capillarity; in fact, that the state of a fluid above that temperature coincided with the properties we call gaseous.'

Annotations in pencil and ink. Includes one figure of Hannay's experimental apparatus and three graphs of experimental results.
