What happen to the water as it is poured into a glass?
Why a meniscus occurs And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus. Cohesion is an intermolecular attraction between like molecules (other water molecules in this case).
Why glass breaks when hot water is poured?
Once you pour boiling water into the glass, the inside part of the glass expands due to heat while the outer layer remains cool. Once exceeded and the glass can no longer contain the pressure, also known as thermal shock, it will start to crack.

Which glass has more water experiment?
If a child is asked “which has more” they’re likely to reply they have the same amout of water, as they look identical. However after pouring the water from one short glass into a tall glass, if you ask the child again they are likely to say the tall glass has more water because it looks bigger.
What happens to glass when you put hot water on it?
Answer: Glass (drinkware) is made up of glass (material) with a certain amount of thickness. When you pour hot water into a glass (which is at room temperature), the inner layer of the glass will absorb heat. When a material absorbs heat, it expands. Glass is no exception to that.
How to pour boiling water into a glass jar?
Before you pour the water into the bottle hold it out in the sink and pour the boiling water on the outside of it first. Afterwards, pour a little bit of boiling water into the bottle shake a bit so it wets the wall and starts heating it slowly and finally proceed to fill it with the boiling water.
Why does water pour out of a container?
If you pour water quickly, water molecules do not get enough time to bond to the container’s surface, and will therefore pour out without any problems. However, when you do it slowly, water spends too much time bonding to the container surface.
What’s the best way to heat up a glass?
Here are some ways to do that: Pour the hot water (very) slowly into the glass. Put a metal spoon in the glass to conduct away some of the heat. Warm up the glass gradually by filling it with 50% room temperature water and 50% hot water.
