is the temperature at which fluid structures crystallize before being solid
Mercury
Glass transition temperature of EVA depends significantly on the VA content. Decreasing VA contents result in a lower Tg. Usually Tg is about -20ºC, for higher VA content is -15ºC, for lower VA content is -40ºC.
Jet Stream The main jet streams are located near the tropopause, the transition between the troposphere (where temperature decreases with altitude) and the stratosphere(where temperature increases with altitude)
Transition
So-called NON-transition metals is not a defined group of elements, other than "All other elements that are NOT transition elements".
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.
Tm is temperature of melting. Tg is glass transition temperature.
The glass transition is a second order phase transition. For materials that have a glass transition temperature, below it they are hard and brittle and above it they are softer and "rubbery".
It doesn't have
It varies. Firstly, it's only present in ferrittic steels like carbon steel, not in most kinds of stainless. Secondly, it depends on the grain size of the steel microstructure, with smaller grains giving a lower transition temperature. The third factor is alloying elements. Silicone and Nickel content tends to raise transition temperature. With modern steels the transition temperature is about -60 degrees celcius. Older steels may have a transition temperature at room temperature, or, more often, at 0 or -10 degrees.
Mercury
no it is a transition metal at room temperature
1257 degrees F.
The -125 degrees indicate the transition temperature of Polyethylene from glass.
cooling rate
Depending on the polymerization, the glass transition temperature will be between -13 C and -8 C; that's 8.6 F to 17.6 F.
