Does water temperature affect surface tension on a penny?
Yes, water temperature can affect surface tension on a penny. As water temperature increases, surface tension generally decreases. This means that with higher water temperature, the water is less likely to bead up and more likely to spread out on the penny, reducing the surface tension.
Does the amount of soap mixed with water affect how well the water will stay on a penny?
Yes, the amount of soap mixed with water can affect how well the water will stay on a penny. Soap reduces the surface tension of water, causing it to spread out more easily. Too much soap can prevent the water from forming a cohesive layer on the penny, causing it to bead up or slide off.
What holds more soapy water or pure water on a penny?
Soapy water will hold more on a penny compared to pure water. This is because the surface tension of soapy water is lower than that of pure water, allowing it to spread out more and cover the penny's surface.
Why does a penny sink faster in water than soap?
The density of a penny is higher.
How do you make a penny float?
One way to make a penny float is by using the surface tension of water. Carefully place the penny on the surface of water in a bowl or cup, making sure it is placed flat. The surface tension of the water will allow the penny to stay afloat.
Does water temperature affect surface tension on a penny?
Yes, water temperature can affect surface tension on a penny. As water temperature increases, surface tension generally decreases. This means that with higher water temperature, the water is less likely to bead up and more likely to spread out on the penny, reducing the surface tension.

Yes, the amount of soap mixed with water can affect how well the water will stay on a penny. Soap reduces the surface tension of water, causing it to spread out more easily. Too much soap can prevent the water from forming a cohesive layer on the penny, causing it to bead up or slide off.
Will different temperatures of water affect the amount of rust on a penny?
no of course it doesnt, gosh
What is the hypothesis of penny drop?
The hypothesis of the penny drop experiment is that the design of the container, the height from which the penny is dropped, and the amount of water in the container will affect whether the penny lands heads up or heads down.
How does the height affect the ammount a penny can hold?
The height of the water in a container affects the surface tension holding the water in place. If the height is too low, it may not be enough to overcome the adhesive forces of the water molecules, causing the water to spill when adding the penny. If the height is too high, the adhesive forces may be strong enough to hold the water with the penny even without surface tension.
Why does a penny hold water?
sit the glass of water on the penny
What happens when you put a penny in water?
When you put a penny in water, its density is greater than that of water, so the penny sinks. This is because the weight of the water displaced by the penny is less than the weight of the penny itself.
How does the juice affect the penny?
The juice's acidity reacts with the copper in the penny, causing it to corrode and form a greenish-blue patina. This is due to the chemical reaction between the acids in the juice and the copper in the penny.
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.
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.
What will make a penny a paperclip a sewing needle and a penny rust faster salt water or plain water?
salt water
Why does a penny hold so much water?
A penny can hold a significant amount of water due to its surface tension properties. The water molecules adhere to each other and the metal surface of the penny, preventing the water from spilling over the edges. This allows the water to collect and form a convex meniscus on top of the penny.
