When a glass of water is turned upside down, the water does not fall out due to the presence of air pressure pushing against the water, creating a vacuum inside the glass. This vacuum holds the water in place, creating a seal that prevents the water from spilling out.
freez the water. after freezing it will be ice then you can turn a glass of water upside down without spilling the water.
When a sealed soda bottle is turned upside down in cold water, the air inside the bottle cools, causing it to contract and create a vacuum. This lower pressure inside the bottle then crushes the bottle as there is greater pressure from the surrounding water, leading to implosion.
Yes, there is a significant difference between a 100°C glass of water and a 200°C glass of water. At 100°C, water is at its boiling point and has turned into steam, while at 200°C, the water would be in vapor form and significantly hotter.
Inside the beaker, the water absorbed heat energy, causing its temperature to rise and eventually boil. The steam formed from the boiling water then condensed on the cooler glass cover, forming water droplets on the bottom due to the temperature difference between the inside and outside surfaces.
If you add more water into the glass once it is full, the water will overflow and spill out of the glass. This is because the glass can only hold a certain amount of water before reaching its capacity.
Because when you turn it upside down, the surface tension of the full glass of liquid, combined with atmopheric pressure provides just enough force to out-do gravity !
The air pressure pushing up on the paper is greater than the gravitational force pulling down on the water, creating a temporary barrier that holds the water in place. This creates a vacuum seal, preventing the water from spilling out when the glass is turned upside down.

One way to turn a glass full of water upside down without spilling it is to place a piece of cardboard or a small plate over the mouth of the glass, then flip the glass upside down while holding the plate/cardboard in place. Once the glass is upside down, carefully remove the plate/cardboard to reveal the water remaining in the glass.
when water is filled up to the brim then water and cardboard are in complete contact with each other , there is no space for air to enter in ...... so it creates a sort of cacuum....and when glass is turned upside down then that created vacuum leads to the hanging of cardboard on its own
because the spoon is concave, making the reflection upside down
This because air is present inside the empty glass which does not let the water to enter theglass . Air also offers a force which is opposite the force of water and does not let the water to enter the glass.
When filling a cup/glass with full water the card/lid will not stay up.
When you dip a glass upside down in a pail filled with water, the air trapped inside the glass creates an air pocket at the top of the glass, preventing water from entering. This is because the pressure of the air inside the glass is greater than the pressure of the water outside. The glass will remain filled with air and no water will enter.
If the glass has a hole in the bottom and you submerge it upside down in water, the water would enter the glass through the hole until the air pressure inside and outside the glass equalize. Once this happens, the water would stay at a level inside the glass equal to the height of the water outside the glass.
The cardboard did not fall to the ground when the glass of water was tipped upside down because the air pressure on the top surface of the cardboard was greater than the water pressure holding it down. This created a force that pushed the cardboard against the glass and prevented it from falling.
He turned upside down, and he had an extra key
