Is there a glass water can go through?
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.
Why is glass insoluble in water?
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.
Which molecules will move faster water molecules in a cup of hot soup or water molecules in a glass of iced lemonade?
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.
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
How does water go through glass?
A glass of water evaporates because the liquid water in the glass is turning into water vapor. It turns into water vapor because the tiny pieces that make up water are moving faster and faster, and then they turn into water vapor.
How do you decrease the number of molecules in a glass of water without changing the number of water molecules?
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
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 are there 8 septillion moleicules in a glass of water?
A glass of water typically contains around 3x10^24 molecules. This number comes from Avogadro's constant, which is the number of molecules in one mole of a substance. Water has a molar mass of approximately 18 grams per mole, resulting in 6.022x10^23 molecules in every 18 grams of water.
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 best explains why water is able to stick to the side of glass?
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.
Is adhesion responsible for the attraction between water molecules and the glass sides of a graduated cylinder?
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.
Is there a glass water can go through?
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.
In a chemical equation can you count the number of molecules?
Yes, you can count the number of molecules in a chemical equation by looking at the coefficients in front of the chemical formulas. Coefficients represent the number of molecules of each substance involved in the reaction. For example, in the equation 2H2 + O2 -> 2H2O, it shows that two molecules of hydrogen combine with one molecule of oxygen to form two molecules of water.

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 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.
