The phase transition temperature is defined as the temperature required to induce a change in the lipid physical state from the ordered gel phase, where the hydrocarbon chains are fully extended and closely packed, to the disordered liquid crystalline phase, where the hydrocarbon chains are randomly...
What is the glass transition temperature of PVC? Polyvinyl Chloride (PVC): High-strength thermoplastic polyvinyl chloride, also known as vinyl or PVC, is frequently used in applications including pipes, medical equipment, wire, cable insulation, etc. The third-most manufactured synthetic plastic polym...
Permabond is often asked by customers for data regarding Tg (glass transition temperature) measurements of our engineering adhesive materials.
How is glass transition temperature measured? How does molecular weight affect the glass transition temperature? Why do elastomers have no glass transition temperature? Does the cooling rate affect the glass transition temperature? How do thermosets behave around the glass transition temperature?
Glass transition is different from actual melting, because there is no latent heat to absorb temperature increases. Unlike a melting substance, a transitioning polymer will continue to heat up as the transition temperature is crossed. The heat capacity of the polymer increases nonetheless, so the pr...

This is a transition from being awake to falling asleep.这是从意识清醒到入睡的过渡期。Heart rate and breathing begin to slow, body temperature falls, and muscles may twitch.心率和呼吸开始减慢，体温下降，而且肌肉可能会抽搐。Stage three is sometimes referred to as delta sleep, because of the ...
Fever is a higher-than-normal body temperature indicating illness, while Temperature is a measure of heat or coldness of an object or environment. Both terms have distinct meanings in health and physics contexts.
A normal internal body temperature for a human is 37 degrees Celsius (98.6 degrees Fahrenheit). This temperature can fluctuate a bit, from about 36.1...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
