What else can I help you with?
When a cup is filled with water with a card on top of it is turned upside down the water does not fall out why?
When the cup is flipped upside down with the card on top, air pressure pushes up on the card, preventing the water from falling out. The air pressure inside the cup is greater than the force of gravity trying to pull the water out. This creates a seal that keeps the water in place until the card is removed.
Does the type of cup affect water's temperature?
Yes, the type of cup can affect the water's temperature. For example, a metal cup may conduct heat better than a paper cup, causing the water to cool down faster. Furthermore, an insulated cup may help maintain the water's temperature for a longer period of time.
Why would a plastic cup freeze water faster?
A plastic cup is a good conductor of heat, meaning it allows heat to transfer quickly out of the cup and into the water, helping it cool down faster. The plastic material also has less thermal mass than glass or ceramic, so it cools down faster itself, helping to cool the water more efficiently.
Why does a cup of milo cool down more quickly when place in a basin of tap water?
Placing a cup of Milo in a basin of tap water allows for better heat transfer between the cup and the surrounding water, causing the Milo to cool down faster. Water has a higher thermal conductivity than air, so it absorbs heat from the cup more efficiently, leading to quicker cooling.
What is heavier bottle of water or cup of water?
A cup of sand, sand sinks in water, thus its heavier.
How does water not spill out when glass covered with card board upside down?
When filling a cup/glass with full water the card/lid will not stay up.
How does a cup of water stick to a piece of cardboard?
You get a peice of cardboard fill a half cup with water and push the cardboard on top and turn it upside down

When a cup of water is dropped does the water in the cup stays in the cup?
If a cup of water is dropped, the water will tend to stay inside the cup momentarily due to inertia. However, once the cup hits the ground and stops moving, the water will then spill out of the cup due to the lack of support from the container.
Describe an experiment to show air has pressure?
1. Take a cup, and fill it about halfway with water. 2. Next cut a piece of paper big enough to cover hole of cup 3. Flip cup upside down securing it with your hand (do this over a sink just in case) 4. Now let go of paper and observe. The paper should stay in place because the air pressure is pushing up against it.
What do the Dairy Queen attendant do when they give the blizzard to the customers?
They turn the cup upside down to show you how thick the ice cream is.
What is the purpose of gravity free water?
how does the gravity free water stay inside the cup
How much water do you add to one bag of cement?
Start with one gallon. Mix the cement with a shovel. Sometimes you may have to add a little more water. You do not want to get it to thin and soupy because it will cause it to loose strength. For best results fill a plastic cup with the mixed cement. Turn the cup upside down and lift the cup up. The final mix should stand close to half the height of the cup.
What rebus for soPUMPKup?
Pumpkin soup. (The word "pumpkin" is turned upside-down to form "pun", followed by "kup" which sounds like "cup".)
If you put a cup of chlorine in 14 inches of water how long will it stay in the water?
that deep-ends on the volume of water
Science projects for kids?
A good one for air pressure in physics is to do an experiment circus where they are in pairs and go around the classroom trying out up to 5 different experiments. One is filling a coke can a third full of water, then heating until steam rises from the can and then using a clamp turn it upside down and into a basin of cold water. Watch the can be crushed by the difference in pressure. Another is filling a plastic cup full of water and placing a piece of card on top then turn the cup upside down and the card will stick. Then, you could try and pull apart two hemispheres in a vacuum.
How do you keep hot water hot in a cup?
try covering the glass, so the heat particles stay inside the cup, and the hot water stays hot.
