Surface Tension
density
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.
Broken glass is a physical change because the glass does not undergo any chemical changes by being broken. The glass could be returned to its original shape through physical means (melt and reform it). Glass is mostly silicon oxides, and the chemical bonds between the silicon and oxygen (which comprise the bulk of common glass) are not affected by breaking the glass.
Some transparent objects are water, air, and clear glass.
Meniscus. Essentially it is because water adheres to the glass.
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
Cohesion
The above property of water is called anomalus
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 property of water that causes it to stick to other things is called cohesion. Cohesion is the result of hydrogen bonding between water molecules, which creates a slight positive and negative charge that allows water to adhere to surfaces. This property is what allows water to form droplets and adhere to surfaces like glass or plants.
Surface tension. This phenomenon is caused by the cohesive forces between water molecules. The surface tension of water allows it to form a slightly raised "bulge" at the top of a glass when overfilled before spilling over.

The polar nature of water: --> unpaired electrons on the oxygen, creates a negative dipole, while the two hydrogens would form a positive dipole. Hence molecules of water are attracted to each other, and pull each other up a thin vertical glass tube (cohesive forces) --> water also sticks to the sides of the vertical glass tube, hence the formation of a meniscus (adhesive forces) With these two forces, you have capillary action, where a thin vertical glass tube can be placed into water and pull up a stream of water. Also! in your drinking straws!
Yes, a glass of water is transparent because it allows light to pass through it easily, making it see-through. The transparency of water allows us to see objects on the other side of the glass.
