A gel is a substance this is mostly a liquid, but behaves as a solid due to cross-linking bonds (usually due to polymerization) that exists in the overall structure.
To show the contrast, a solid is usually a substance held in some sort of crystalline form (be it due to ionic, covalent, or hydrogen bonds), which makes the overall structure rigid, so that it does not flow.
Whereas, the molecules in a liquid can flow much more easily, moving past each other, and they are not locked in a crystalline form.
In a gel, however, while the molecules can flow past each other, in the absence of external forces, they usually tend to lock into place, weakly bonded to one another, resulting in zero flow. When you add external forces (compression, shearing, etc.), the molecules can move past each other again, and the substance can flow.
Imagine Gelatin (Jello, etc.) as an example. Without any external forces, it sits in place, locked into a molded form. However, if you press or squeeze it, it can easily deform. If you have it in a large container with a plunger behind it, and a smaller opening at the end, you could push the plunger, and the gelatin will extrude from the small opening, allowing it to flow through that opening. "Flow" being the key word here.
The same goes for gel deodorants. They are normally in one form. When you add shear forces, rubbing it on your skin, it will flow from the seemingly solid form to smear onto your skin much like a liquid.

What are the forms of chemistry?
Different typee of classifications: - organic and inorganic - acids, bases, salts, oxides - natural elements and artificial elements - metals, metalloids or nonmetals - covalent or ionic etc.
Is gel an adverb?
No, gel is not an adverb at all.The word gel is a noun and sometimes a verb.
What is NIE mean in chemistry?
IE in Chemistry stands for ionization energy. It is the energy needed to remove electrons from an atom.
How do you use the word gel in a sentence?

Her favorite kind of toothpaste is a minty green gel. That stain fighting gel removed mud and grease from his pants. Let the mixture gel in the refrigerator for about an hour.
What does the gel in a 'vacutainer' tube consists of?
Some vacationers contain additives coated along the inside of the container without any gel. The gel in a vacationer is an intermediate density between blood cells and serum so that when centrifuged, the gel can keep the blood cells and serum from remixing. The gel consists of semi-solid inert gel composed of a number of compounds.
Is hair gel and ionic Bond?
Hair gel and ionic bonds are not the same thing. Hair gel is a styling product used to hold hair in place, while ionic bonds are chemical bonds that form between atoms by transferring electrons. Hair gel works by creating a mechanical bond with the hair strands, not through ionic bonding.
Is hair gel and ionic compound?
Hair gel is not an ionic compound. It is a mixture of polymers, water, and other ingredients that help to style and hold hair in place. Ionic compounds are typically formed by the attraction between positively and negatively charged ions.
What are three major bond in chemistry?
covalent hydrogen and ionic
Will sugars and salts dissolve in hair gel?
Salts are more likely to dissolve in hair gel compared to sugars. Hair gel typically consists of a water-based or alcohol-based solution, which can dissolve salts due to their ionic nature. Sugars, being non-ionic compounds, are less likely to dissolve in hair gel and may remain as suspended particles.
What are some common ionic bonding questions that students often struggle with in chemistry?
Students often struggle with understanding how ions form, predicting the charges of ions, determining the formula of an ionic compound, and balancing chemical equations involving ionic compounds in chemistry.
What is zinc sulfate in chemistry?
Zinc sulfate is an ionic chemical compound.
Is hairgel an ionic compound?
Hair gel is typically not an ionic compound. It is usually made up of polymers and other organic molecules that are covalently bonded, rather than having ionic bonds.
Is hair gel a silver bracelet motor oil or baking soda a ionic compound?
baking soda
Where do you find ionic bonds?
Frequently in inorganic chemistry. Like Sodium chloride NaCl
What are three classification schemes used in Chemistry?
Acid and Base. Ionic and non-Ionic [neutral]. D(dextro)-rotary and L(levo)-rotary.
Who is an ionic bond scientist?
There is no specific study of ionic bonds, but being most common in inorganic chemistry probably an inorganic chemist would be most interested.
