What is the control on the penny water drops experiments?
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.
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?
Consider drops of water that leak from a dripping faucet As the drops fall they?
get farther apart
Drops of water on a cold can are?
condensation
How many drops of water is equal to one liter?
"Drops" come in many different sizes (the biggest raindrops have as much water as a thousand of the smallest raindrops and the smallest raindrops are a million times as massive as the typical cloud or fog droplet). However, some old cookbooks reckon that there are 72 drops to a teaspoon and there are roughly 200 teaspoons to the liter, so 14,400 drops per liter is a pretty close answer. You could call it 15,000 and not be far wrong.
How surface tension behaves?
for example, if drops of water are placed on the top of a penny, the surface tension is going to hold the drops on top of the penny. when the penny can hold no more, it will all overflow. make sense?

What is the control on the penny water drops experiments?

What variables may play a factor in the amount of drops the penny hold?
Several factors can come into play here.The size of the dropsHow fast the liquid is being droppedWhat type of liquid is being usedThe temperature of the liquidThe termperature of the pennyIf the penny was clean or dirtyThe height the drop falls fromAny of these things can have an effect an expansion of the liquid, surface tension, and splash.
How many drops can you hold on a penny list one uncontrolled variable?
The penny's state of corrosion.
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 a penny hold on its surface?
Water has a surface tension. When dropping water on a penny, people usually underestimate how much water the surface of a penny can hold. The surface tension of water is strong on a smaller surface, and when dropping water on the surface of a penny, towards 20 drops the water on the penny will look like it is bulging out a lot. It really depends, depending on which side of the penny you are using, it ranges from 6 to even 34 drops using a simple eyedropper. Because eyedroppers do not produce the exact same size of drops every time, the result is not very accurate. To be even more accurate, scientists use accurate distributing machines and a very new penny to determine how many drops of water it can hold without vibrations. There could be certain amounts of grime and dirt on a penny, depending on how old it is, which can affect how much water can be put onto it. Different types of water can also change how much a penny can hold. Tap water has certain amounts of chemicals in it, and that could also affect the weight and surface tension of the water on the penny. The height of which the water comes off from matters too, the more force of the water that comes down, the more likely the water on the penny is to splash and spill. The place the water lands on also has an effect on it. To be even more accurate, light has a mass. If light shines directly at the water on a penny, it could push it a tiny bit. This change is impossible to see, and it has basically no effect on the penny or water at all whatsoever. Remember, all tests may not be 100% accurate, and there may always be a chance that there is a better way to make a penny hold more droplets of water than the presumed "most advanced and accurate" way.
Why does a penny hold water?
sit the glass of water on the penny
Why does your penny hold so many drops?
it is big inside but small out side
Drops on a penny?
The surface tension of water allows drops to sit on a penny without overflowing. This is due to the cohesion of water molecules, which causes them to stick together and form a dome shape on the penny. Additionally, the adhesive forces between the water and the penny help to keep the water droplet in place.
What property of water allowes so many drops of water to stay on a penny?
adhesion
