What else can I help you with?
Why when placed in a glass tube water touching the glass is pulled slightly upward?
Meniscus. Essentially it is because water adheres to the glass.
What do you call the ability of water to climb upward in narrow tubes?
The adhesive forces of the polar water molecules to the glass surface, breaks the surface tension of the water and causes a capillary action up the sides of the tube.
Why does a grape shrivel up when put in a glass of salt water?
Because the solute concentration in the salt water is higher then other solutions, in this case, a grape. the moisture is basically sucked out of the grape and the grape shrivels
Ordinary glass is filled to the brim with water If the temperature decreased how much water could be added to the glass?
It depends on: -The current temperature of the water. (If it was already cold, the water would probably decrease because both heat and cold causes water to increases) -The size of the glass. -How much the temperature decreases.
Why does dew produced when ice is in a glass?
Because the surface temperature of the glass gets colder than the dewpoint temperature of the air. Therefore the relative humidity goes over 100% on the glass causing water vapor in the air to condense into liquid water on the glass.
What amount of water make a higher note in a glass?
THE GLASS WITHOUT WATER MAKE A HIGHER THE GLASS WITHOUT WATER MAKE A HIGHER THE GLASS WITHOUT WATER MAKE A HIGHER THE GLASS WITHOUT WATER MAKE A HIGHER THE GLASS WITHOUT WATER MAKE A HIGHER
What glass of water makes a higher pitch more or less?
A glass with less water will make a higher pitch when tapped, while a glass with more water will make a lower pitch. This is because the amount of water affects the frequency of vibrations produced by the glass when hit.
Does a piece of glass float?
No, glass sinks in water because it is denser than water. The density of glass is higher than that of water, causing it to sink rather than float.
If you drop a marble into a glass of water the marble will sink because its?
Because the marble has a higher density than the water does
Would water evaporate faster in a wide glass than in a narrow?
Water evaporate faster in a wide glass than in a narrower glass.
Does liquid water rise higher in a narrow tube or a wide tube?
Rise or fall of liquid in a small passage or tube. When a glass tube of small internal diameter is inserted into water, the surface water molecules are attracted to the glass and the water level in the tube rises. The narrower the tube, the higher the water rises. The water is said to "wet" the tube. Water will also be drawn into the fibres of a towel, even if the towel is in a horizontal position. Conversely, if a glass tube is inserted into mercury, the level of the liquid in the tube falls. The mercury does not wet the tube. Capillarity is caused by the difference in attraction of the liquid molecules to each other and the attraction of the liquid molecules to those of the tube.
Does glass bangle sink or floats in water?
Glass bangles are denser than water, so they typically sink when placed in water. This is because the density of the glass is higher than that of the water, causing it to displace less water and sink.
Does Water evaporate faster in a wide glass or narrow glass?
A tall, skinny glass will freeze water faster than a short, wide glass.This is because the tall glass allows convection (cold particles in the air to transfer cold to the water particles in the glass) to take place between more particles at once due to a tall glass having a larger surface area.
When light rays pass from water into a certain type of glass the rays refract toward the normal. Compare and contrast the speed of light in water and in glass.?
The speed of light in water is slower than in glass because glass has a higher refractive index. When light rays pass from water into glass, they slow down due to the denser medium, causing them to refract towards the normal. Glass slows down light more than water because of its higher optical density.
Why does a piece of glass float in mercury but sinks in water?
Glass floats in mercury because mercury is much denser than glass, creating a buoyant force that allows the glass to float. In contrast, water is less dense than glass, causing the glass to sink due to its higher density. The buoyant force in water is not enough to support the heavier glass object.
Does water evaporate faster in a dark glass or clear glass?
It depends on how much light is shining on the glass. If there is a lot, then the water in the dark glass will evaporate faster because the temperature will be higher. If there is no light, then it does not matter.
Why Pitch of sound in half glass water is more than full glass of water?
The pitch of sound is higher in a half glass of water because the smaller amount of water leaves less space for sound to travel, causing the sound waves to bounce more frequently off the glass walls and create a higher frequency sound. In a full glass of water, the sound waves are able to travel more freely through the larger volume of water, resulting in a lower pitch.
