Explain why the melting point of pure phthalic acid is higher than that of pure naphthalene when both have nearly the same weight. How does adding salt affect the freezing and melting of water? Why does water boil at a higher temperature than butter, which is non-polar?
Explain why the boiling points of the components of a mixture should differ by at least 40 degrees Celsius in order to get an effective separation by simple distillation. Why does AsH3 have a higher boiling point than PH3? How does salt affect the boiling point of water? (in si...
Place melted butter in the bottom of a large bowl. Stir in herbs, if using, salt, and pepper. Add potato slices and mix to evenly coat them. Spread potato slices and all of the good stuff at the bottom of the bowl in a 9×13 (quarter-sheet) metal (a glass baking dish shouldn’...
melt·ing point (mĕl′tĭng) The temperature at which a solid becomes a liquid. For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form. The melting point of ice is 32°F (0°C); that of iron is 2,797°F (1,535°C...
temperature and pressure reach a certain point, the ice turns to gas and evaporates, leaving tiny air pockets in the ice cream which give it the crumbly texture. It’s interesting that the freeze-dried ice cream comes out of the machine looking identical to the frozen product it started as...
