Addiction is a chronic brain disorder and not simply a behavior problem involving alcohol, drugs, gambling or sex, experts contend in a new definition of addiction, one that is not solely related to problematic substance abuse.he disease creates distortions in thinking, feelings and perceptions, which drive people to behave in ways that are not understandable to others around them, Hajela said in a statement. Simply put, addiction is not a choice. Addictive behaviors are a manifestation of the disease, not a cause..
The upper critical solution temperature (UCST) or upper consolute temperature is the critical temperature above which the components of a mixture are miscible in all proportions. solid state example is the palladium-hydrogen system which has a solid solution phase (H 2 in Pd) in equilibrium with a hydride phase (PdH n) below the UCST at 300 Â°C. Above this temperature there is a single solid solution phase.
Saturation temperature means boiling point. The saturation temperature is the temperature for a corresponding saturation pressure at which a liquid boils into its vapor phase. The liquid can be said to be saturated with thermal energy. Any addition of thermal energy results in a phase transition.he boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure.
