How many liters of water produces a ton of paper?
None. Water contains no fibres and so no amount of water can make paper.
What changes shape when placed in a different container?
water and gas
What is negative about paper?
The paper is probably negatively charged, polar too, hence absorbs water.
Will a paper float?
As long as it can displace a volume of water equal to its mass (ie its density is less than that of the water) it will float. Most paper will have a density less than that of water (or can be so folded) so will float.
How do you make a water bomb out of paper?
The first link is a very accurate instructional video, the second is a variation to make with printed paper that actually comes out to be a globe. Any paper can be used, keeping in mind how long you want it to hold water: thin paper like newspaper pops easily but leaks water very quickly, most coated magazine pages will hold the water for a long time but don't pop easily until the water soaks through for a while.
Is greased paper hydrophilic?
Greased paper is typically hydrophobic because the grease creates a barrier that repels water. However, some water may be absorbed by the paper itself depending on its porosity.
Would a paper clip sink or float?
A paper clip is denser than water, so it would sink if placed in water.
Place a steel pin on a filter paper and put it gently on the surface of china dish. filter paper will absorb water but the pin still floats. why?
Surface tension of the water
What is a prepared slide on a micro scope?
A prepared slide for a compound light microscope is composed of a viewing sample suspended in a drop of distilled water, which has been placed on one glass slide. A second glass slide will be placed on the first slide and any residual water will be gently soaked up by a paper towel.
What happen if the needle place on a small tissue paper and very gently put the paper on the surface of water?
The tissue paper will likely float on the water's surface as long as the needle does not break through the paper. This is due to surface tension, which allows light objects to float on water.
Do paper clips placed in water overflow it?
it depends on how many you put in the water. But if there's enough, yes.
Why does a paper boat float when it is placed in water?
A paper boat floats on water because of buoyancy, which is the force that water exerts on objects placed in it. The shape of the boat traps air inside it, which makes it less dense than water and allows it to float. Additionally, the weight of the paper boat is spread out over the surface of the water, creating an upward force that counteracts gravity.
How do you remove fingerprints from paper?
To remove fingerprints from paper, you can gently rub a soft white eraser over the affected area. Be careful not to rub too hard as this could damage the paper. You can also try using a clean, soft cloth lightly dampened with water to gently wipe the fingerprints away.
Can you float a paper clip?
Yes, a paper clip can float on the surface tension of water if it is carefully placed on the water. The surface tension of water allows certain lightweight objects, like paper clips, to be supported without sinking.
Why does cobalt chloride paper change from blue to pink when it is placed on a leaf or a plant?
The change in color of cobalt chloride paper from blue to pink when placed on a leaf or plant is due to the presence of water vapor released during photosynthesis. The paper is sensitive to moisture, and the water vapor from the leaf causes it to undergo a chemical reaction, changing its color. This color change is a simple and quick way to detect the presence of moisture or water in a sample.
Does aluminum foil or paper towels keep water placed in a cup and ice colder?
alot
What is the hypothesis of make a paper clip float?
The hypothesis could be: If the paper clip is placed in a container of water and a material with a lower density than water is introduced, then the paper clip will float on the surface of the water due to the buoyant force acting on it.
