Specific gravity (relative density) The specific gravity of a gas, Î³, is the ratio of the density of the gas at standard pressure and temperature to the density of air at the same standard pressure and temperature. The standard temperature is usually 60Â°F, and the standard pressure is usually 14.696 psia.

Trainee appointments are usually in one-year increments; new appointments must be at least nine months except when we've approved a short-term training position. A trainee can remain in a program for a maximum of five years for predoctoral trainees; three years for postdoctoral trainees.
