Why is glass hydrophillic?
Glass is hydrophilic primarily due to its polar surface, which contains silanol (Si-OH) groups. These groups can form hydrogen bonds with water molecules, allowing water to spread and adhere to the glass surface rather than bead up. The presence of these polar sites enhances the interaction between glass and water, leading to increased wettability. This property is essential in various applications, including labware and coatings.
When rubbing a wool sock on a glass rod what transfers to the sock?
The described action will leave the wool sock positively charged, as electrons will be transferred to the glass rod.
When substance attracted to water is called?
A substance that attracts water molecules is hydrophillic, hydro meaning water and phillic meaning attracted to. The opposite would be hydrophobic, hydro meaning water and phobic meaning scared of.
What property is described by a steel blade can be scratch glass?
The property described is hardness, which refers to a material's resistance to scratching or indentation. In this context, a steel blade's ability to scratch glass indicates that the steel has a higher hardness than that of glass. This property is often measured using the Mohs scale of mineral hardness, where glass typically ranks around 5.5. Therefore, the steel blade must have a hardness rating greater than this to effectively scratch the glass.
Why is glass discribed as hydrophilic?
Glass is described as hydrophilic because it has a tendency to attract and interact with water molecules. This is due to the presence of hydroxyl groups on the glass surface, which allow for hydrogen bonding with water molecules. As a result, water spreads out and forms a thin film rather than beading up on the glass surface.
Do hydrophobic or hydrophillic material dissolve in water?
Hydrophobic participles are "running" away from water. Try pouring some oil into a glass of water and you will see what I mean. Hydrophillic participles, on the other hand, attract water and soon a hydrophillic participle will be completely surrounded by water molecules, Which is a fancy way of saying that it'll dissolve.
Is oxytocin hydophillic or hydrophobic?
Hydrophillic
What is the most reasonable unit measure a small glass of grapefruit juice?
-- The height and diameter of the glass can best be described in centimeters. -- The thickness of the glass can best be described in millimeters. -- The total volume of the glass, as well as the volume of grapefruit juice, can best be described in milliliters. -- The temperature of the grapefruit juice can best be described in Kelvins (degrees Celsius). -- The specific gravity of the juice is dimensionless. -- The acidity of the juice is best described in terms of its 'pH'.
Where is hydrophillic portion found?
Hydrophillic means water loving matter. In dry seeds this matter is present which prompts the process of imbebition at the time of seed germination.
Is there such thing of self cleaning windows?
Self cleaning glass DOES exist, kind of. In theory, glass which is either fabricated with a hydrophillic surface (i.e. etremey smooth and water-loving) has self cleaning properties. Glass can also be treated by the consumer of a professional to be hydrophillic or hydrophobic (water hating). Here's the catch though... "Self Cleaning" glass needs exposure to a great amount of water to actually be self cleaning. If a window that is purportedly self-cleaning is not exposed to enough rain / water to sheet all the dirt and debris off the window, then the dirt will remain on the glass, henceforth, the glass will still be dirty. My suggestion, unless you want to hose down all of your windows every few weeks, save your money by buying regular glass and hire a professional window cleaner to handle your windows for you!
What property is described under a magnifying glass that sugar appears to be made of tiny cubes?
The property is described under a magnifying glass that sugar appears to be made of tiny cubes is crystal form.
What is the sound of broken glass called?
The sound of broken glass is often described as a "shattering" sound.

What does the word hydrophillic mean?
having a strong affinity for water
Is there another word for a glass container?
They are generally described by shape not mat'l.
Are fats hydrophillic?
No. Hydrophillic freely associates with water, readily entering into solution, and water loving. Fats, or lipids, are hydrophobic, which are incapable of freely associating water molecules, insoluble, and water-fearing.
