SINCE reading Principal Guthrie's first letter on this subject (vol. viii. p. 67), I have thought of several ways of investigating the equilibrium of temperature in a gas acted on by gravity. One of ...

A supercritical fluid refers to a state in which the temperature and pressure of a substance exceed its critical point, where ...

One of the major advantages of differential scanning calorimetry (DSC) is that it depends on heat measurements, which make characterization of native biomolecules possible. It is not necessary to have ...

The yield of ammonia changes with changes in pressure and temperature It also shows that at any given pressure (ie following a vertical line up from the x-axis), as the temperature decreases, the ...
