condensation
It's called condensation. it's not sweat. There's microscopic liottle drops of moisture in the air that get collected toward cold areas, on a hot day, it has no where to go but toward a cold glass of water.
Water has both cohesive and adhesive forces. They are similar.The cohesive of water describes how the molecules of water are attracted to one another. We observe the cohesive forces of water when we see a drop of water sitting on a surface. The water does not spread because the molecules are attracted to one another. Surface tension of water is due to its cohesive properties.The cohesive forces of water are due to hydrogen bonding between molecules.Adhesive properties of water are how the molecules are attracted to other substances. We observe the adhesive forces of water when we see the edge of water in a glass is attracted up on the sides of the glass. This is most apparent when the diameter of the glass vessel is less than a centimetre. It is called a meniscus. Trees use this adhesive property of water to help suck water up from the ground. If the diameter of the glass is small enough, as in a glass capillary, the water will rise up the tube by itself due to adhesive forces.
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
the water molecules in your breath condenses as moisture on the glass.
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
Water is able to stick to the side of glass due to adhesion, which is the attractive force between water molecules and the molecules of the glass surface. This is also aided by the polar nature of water molecules, which allows them to form hydrogen bonds with the molecules in the glass, creating surface tension that holds the water in place.
Yes, adhesion is responsible for the attraction between water molecules and the glass sides of a graduated cylinder. Adhesion is the force of attraction between different molecules, in this case, water molecules and the glass molecules. This attraction causes the water to stick to the glass surface instead of forming a perfect dome shape.
Yes, water can pass through glass since it is a porous material. This property allows water molecules to move through the tiny spaces between the glass molecules.
The glass is not actually "sweating." What you are seeing is condensation of water molecules from the air onto the glass's surface. Because the water in the glass has less energy than the water in the air (it's cooler), energy from the water molecules in the warmer air is given up to warm the cooler water in the glass. This loss of energy results in the air water molecules' inability to break the number of hydrogen bonds between themselves necessary to remain in the gas phase and ultimately the condensation of water onto the outside of the glass surface.
The meniscus is created by adhesive forces between the glass and the water. THis means that the water water molecules are attracted to the glass so they can creep up the glass to a small degree. The water molecules are also attracted to each other through hydrogen bonding. These are called cohesive forces and they allows the water that creeps up the glass to bring other water molecules with them. The cohesive forces and adhesive forces can only resist gravity to a certain degree so in the middle the liquid curves downward.
Glass is insoluble in water because it lacks a crystal structure, making it difficult for water molecules to break apart and dissolve its components. Additionally, glass is composed of strong covalent bonds that are not easily broken by the polar nature of water molecules.
When water is in an open container, some of the water molecules will have higher kinetic energy and will escape into the air as vapor. This process is called evaporation. As these water molecules leave the surface of the water, they cause a cooling effect on the remaining water molecules, which can also contribute to further evaporation.
Water-fearing molecules are called hydrophobic molecules. These molecules do not interact or mix well with water due to their nonpolar nature.
This depends. If the molecules are of different kinds (ie: Water and Glass), then it is called adhesion. If they are of the same kind, it is called cohesion.The tendency of molecules of the same kind to stick to one another is known as cohesion. This is what keeps the molecules together a good example being in water.
Water molecules in a cup of hot soup will move faster than water molecules in a glass of iced lemonade. The higher temperature of the hot soup provides more energy to the water molecules, causing them to move faster.
when sodium silicate is fused it is called water glass..........
