Cold finger used in sublimation.The raw product (6) is in the bottom of the outer tube (4) which is heated (7) while under vacuum (through side-arm 3). The sublimated material collects (5) on the cold finger proper, cooled by a coolant (blue) circulated through ports 1 and 2.
Sublimate also refers to the product obtained by sublimation. [2] [3] The point at which sublimation occurs rapidly (for further details, see below) is called critical sublimation point, or simply sublimation point. Notable examples include sublimation of dry ice at room temperature and atmospheric pressure, and that of solid iodine with heating.
The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water ice and leaves no residue as it changes state. [4] Its enthalpy of sublimation is 571 kJ/kg (25.2 kJ/mol, 136.5 calorie/g). Dry ice is non-polar, with a dipole moment of zero, so attractive intermolecular van der Waals forces ...
When cleaning the enameled cast iron routinely after a cooking session or a recipe, remember a few important tips. First, avoid washing the enameled cast iron immediately after cooking in it.
This creamy slow-cooker leek soup showcases leeks’ mild onion flavor, enhanced by plenty of fresh and dried herbs and with potatoes adding texture and body.
A dishwasher containing clean dishes An open dishwasher. A dishwasher is a machine for cleaning dishware and cutlery automatically. Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 45 and 75 °C (110 and 170 °F), at the dishes ...
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1273 ahead. Let's start with a few hints.
This can be done by a desalination process. Desalination is often completed in bath changes using clean water. Sometimes disinfectants (fungicides or algaecides) are added to prevent the development of damaging organisms. However, the most commonly used and recommended because of its lesser toxicity is a mixture of boric acid and borax.
