Ideally, everyone performing the experiment would include the following:
- distilled waterThere are a lot of factors involved. The cohesion and adhesion ('stickiness') of water molecules can be effected by things like oils (on surface pennies from peoples' skin) and other contaminates on the penny.
The size of the dropper or pipette will determine the size of each water droplet - the larger the drop, the fewer number of drops will fit on the penny.
The manner in which the water is added to the penny is also a factor. Water has a cohesive nature (the molecules are kind of like magnets and are attracted to one another). Therefore, if the drop from the pipette is allowed to touch the water already on the surface of the penny, the water can be 'pulled' out of the dropper. When this happens, the size (volume) of the drop is not always the same - it could be a very small amount (which will result in a very large number of drops), or a large amount.
Ideally, everyone performing the experiment would include the following:
- distilled water
- same type/size of calibrated dropper/pipette
- same date of penny
- penny cleaned as thoroughly as possible using same cleaning procedure
- same 'dropping' procedure

How many pennies in a oz?
There are approximately 28.35 grams in an ounce. Since a penny weighs about 2.5 grams, you can fit roughly 11.3 pennies in an ounce. However, since you can't have a fraction of a penny, you can say there are about 11 pennies in an ounce.

four
What is the control and independent and dependent variable in the 'how many drops of H2O can fit on a penny'?
The controlled variable is the penny. The independent variable is the water. The dependent variable is the amount of water able to fit on the penny.
Is the variable alcohol when using water and alcohol to see how many drops can fit on a penny?
Yes, in this experiment, the variable "alcohol" refers to the liquid being tested to see how many drops can fit on a penny. By changing the type of alcohol used, you can observe how it affects the number of drops that can fit on the penny due to variations in surface tension and viscosity.
How many drops of water can fit on a US penny?
Approximately 30 to 35 drops of water can fit on a US penny before spilling over. The surface tension of the water allows it to form a dome-like shape on top of the penny, holding more drops than you might expect.
How many drops of water can fit on a penny research paper?
Alot of drops fit because if you keep the surface tension from moving then you could put as much drops as you can.] ==If you put a penny on a flat surface and keep its tension and keep the penny from moving you can put as much drops as you can till it leaks off. You cant put as much as you want cause the penny will overflow. its not a big object?
How many drops of water will fit on a quarter?
Approximately 30 to 40 drops of water can fit on a quarter, depending on the size of the drops and the condition of the coin's surface.

When this happens, the size (volume) of the drop is not always the same - it could be a very small amount (which will result in a very large number of drops), or a large amount. Soap causes the cohesiveness ('stickiness') of the water molecules to decrease so they are not as strongly attracted to each other. Because of this, when soap is added to the water the number of drops that can be placed on the penny will decrease. The water molecules can't 'stick' together as well, so the water on top of the penny spills off sooner than it would with non-soapy water. Ideally, everyone performing the experiment would include the following: - distilled water (to start with) - same type/size of calibrated dropper/pipette - same date of penny - penny cleaned as thoroughly as possible using same cleaning procedure - same 'dropping' procedure
How can so many drops of water fit on a penny?

How many drops of water can fit in a mouth?
On average, a person's mouth can hold about 1-1.5 teaspoons of water comfortably. This would equate to roughly 75-115 drops of water, depending on the size of the droplets.
Why does a penny hold more water drops than drops of oil?
Small drops of liquids tend to be spherical because of their surfacetension. Surface tension is the result of intermolecular attractingforces. When you put a small drop of a liquid on a solid surface, theinermolecular forces of the solid surface will tend to attract the liquidmolecules. Depending on the magnitude of the different forces, the solidsurface will present certain degree of 'wettability'. If you compare howa drop of water sits on a clean penny and on a penny that you rubbedwith your fingers, you'll notice that the drops contact angle differ.The drop on the clean penny will cover more contact area (more wettablesurface) than the drop on the 'oily' penny (less wettable surface). Oilreppels water because the intermolecular forces between the water andoil molecules are very weak compared to the intermolecular forces betweensimilar molecules.Now, water intermolecular forces are paricularly strong, and so the dropof water on the penny will resist more than the oil molecules to be spreadedon the surface of the penny. Oil drops tend to wet more the surface of thepenny and will tend to occupy more area. And so you'l get fewer oil dropson the penny's surface.
