No, sodium carbonate does not sublime because it decomposes at high temperatures into sodium oxide and carbon dioxide gas rather than transitioning directly from a solid to a gas phase. Sublimation is the process where a substance goes from a solid directly to a gas without passing through a liquid phase.
Oh, dude, like, totally! Alum is sublime, but not in a "wow, that's amazing" kind of way. It actually sublimes, which means it goes from a solid to a gas without melting first. So, yeah, alum is totally sublime in a chemistry kind of way.
A liquid lens is one where, rather than solid glass or plastic, the light is refracted through a liquid substance.
Toothpaste is typically considered a semi-solid or gel-like substance, rather than a liquid, due to its thicker consistency.
When a substance is boiling, it stays at a constant temperature because the heat energy is being used to convert the liquid into vapor, rather than increasing the temperature of the substance. At the boiling point, the substance's molecules have enough energy to overcome the intermolecular forces keeping them together as a liquid. This leads to the phase transition from liquid to gas.
I can dissolve more sugar in hot tea rather than cold tea.
The boiling point of twice the amount of liquid will remain 150 degrees. The boiling point of a substance is determined by the chemical properties of the substance itself, rather than the quantity of the substance.
Cytoplasm is a semi-fluid substance that resides inside a cell. It is neither solid, liquid, nor gas, but rather a gel-like substance that contains various organelles and dissolved molecules necessary for cellular functions.
Quicksand is not a liquid, but rather a wet mixture of sand, clay, and water that forms a semi-solid substance. When disturbed, quicksand can behave like a liquid, causing objects or people to sink into it.
it is a mixture..homogenous and a colloid one....
During melting, energy is absorbed to overcome the intermolecular forces holding the substance together instead of increasing the temperature. This energy is used to separate the molecules within the substance rather than increase their kinetic energy and raise the temperature. Once these forces are overcome, the substance can transition from a solid to a liquid at a constant temperature.
Eyeballs are neither solid nor liquid, but rather a gel-like substance. The vitreous humor and aqueous humor inside the eyeball give it a somewhat firm but flexible structure.
