If you mix oil and water together, the mixture contains two liquid phases because the oil will float on top of the water because of oil's lower density.They're not going to mix together like alcohol and water do.You can see the boundary between them, and in fact they’re mechanically ...
From the corresponding freezing-point depression of the binary systems the salting-out constantsk s were calculated. The effect of ionic size was investigated withtert-butanol, and the effect of alcohol chain length with NaCl. The trends ofk s with ionic size are similar to those of typical ...
A liquid's freezing point is -38 degree Celsius and its boiling point is 37 degree Celsius. What is the number of kelvin between the boiling point and the freezing point of the liquid? What is the boiling temperature of water in both Fahrenheit and Cel...
The answer, Macquarrie says, is 24 degrees Fahrenheit. That’s right, when the ideal cocktail hits your lips, it should be 8 degrees below the freezing point of water (an achievement made possible, of course, by the fact that the freezing point of pure ethanol alcohol is -114 degrees)....
