This code was widely used in the 1970s, but is much less used today. (The terms bandana code, hanky code, or flagging are much more widely used among those in the leather subculture than the term handkerchief code.) It should be noted that this code has come into more general usage today.
Generally speaking, solid turns to a liquid at its melting point. Ice turns to water at 0 degrees Celsius. Chocolate melts at 25 degrees Celsius- Yum! Ice (solid) thaws when the temperature rises above 32 degrees Fahrenheit, becoming water (liquid). Other solids (oddly) vary. Generally speaking, solid turns to a liquid at its melting point. Chocolate melts at 25 degrees Celsius- Yum! Ice (solid) thaws when the temperature rises above 32 degrees Fahrenheit, becoming water (liquid).
A system under pressure can handle higher temperatures, and offers a higher static boiling point. Most liquids have a specific boiling point, which is the temperature at which the liquid begins to. change to a gas. If pressure is applied to the liquid, it must become hotter before it can boil. Pure. water in a cooling system will boil (at sea level) at 212Â° F. At higher altitudes, atmospheric pressure.
