WebFlash Points of Isopropanol (2-Propanol) based Water Solutions. The flash point of a chemical is the lowest temperature where it will evaporate enough fluid to form a combustible concentration of gas. The flash point is an indication of how easy a chemical may burn. Flash Point. Isopropanol Concentration. (% by volume) WebFreezing-point depression is a drop in the minimum temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added. Examples include adding salt into water (used in ice cream makers and for de-icing roads), alcohol in water, ethylene or propylene glycol in water (used in antifreeze in cars), … joy pelly facebook

While the freezing point of pure glycol is only -39° F, the synergy between glycol and water results in a much lower freezing point. This is very important for closed-loop systems that may be exposed to freezing conditions. WebFeb 3, 2024 · This solute lowers the freezing point of the water, preventing the engine from cracking in very cold weather from the expansion of pure water on freezing. ...
