Why does a glass of water sweat?
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.
2 How can you explain Cohesion and adhesion in term of water molecules?
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.
If water spreads out on a glass plate is this an example or cohesive or adhesive force?
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.
When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
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.
When you beathe on cold window what happens?
the water molecules in your breath condenses as moisture on the glass.
Which property allows water to stick to glass?
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
Why does water wet glass and mercury does not?
Water wets glass because the force of adhesion between the glass molecules and water molecules is greater than the force of cohesion between the water molecules and glass molecules. Mercury does not wet glass because the force of cohesion is greater than the force of adhesion
Why does glass of water sweat?
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.
What forces create the meniscus you see at the top of a liquid when you measure it?
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.
Why a drop of water put on a glass plate spreads?
because the cohesion of water molecules is less stronger than the adhesion of the water molecules
The tendency of molecules of the same kind to stick together is called?
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.
Why does a glass leave a ring on the table?
A glass will leave a ring on the table because it drips water. This water gets under the finish of the table and leaves a ring.
When you put cool water in the glass why the outside vapour appears?
as the air molecules are free to move , when we pour cold water in glass its surface become cooler than the room temperature , thr air molecules stick with the walls of glass and due to low temperature there these air molecules deposit there.
What happens when you leave a glass of water in the closet?
It will get foggy

What is water glass?
when sodium silicate is fused it is called water glass..........
