If you mean why does the water drop grow so large on top of a penny, the answer has to do with the surface tension of water. Water "likes" to stick together, so it pulls inward and keeps tightly attached to each molecule. This allows a large droplet to grow before it runs off.
What else can I help you with?
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.
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.
Would a penny sink or float in water?
When an object of volume V is submerged in a liquid, the object experiences an upward force equal to the weight of the fluid it has displaced (the weight of a volume V of fluid). Oil is less dense than water (the oil floating on the surface of the Gulf of Mexico after the Deep Horizon catastrophe is an example of this), so a given volume of oil weighs less than the same volume of water. This means that a penny of volume V submerged in oil feels the weight of gravity pushing it down, and the weight of a volume V of oil pushing it up. The upward weight pushing the penny up is less in oil than in water, so the penny will sink faster in water, theoretically.
Why water can hold so much heat?
Water has a high specific heat capacity due to its hydrogen bonding structure. This allows water to absorb and retain heat energy without large fluctuations in temperature. The hydrogen bonds need to break and reform, absorbing heat in the process, which contributes to water's ability to hold heat.
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.

Does water of a bathtub hold 350 ml?
Assuming that you are asking does a bathtub hold 350 ml of water: 350 ml of water is not very much water, a typical water bottle that you hold in your hand has more than 350 ml of water in it, so a bathtub big enough to hold a person will hold many times that much.
How much water does warm air hold?
alot but non couse if it have to much it will brake so hehehehehehe so thats my answer
Why does your penny hold so many drops?
it is big inside but small out side
Is putting water on a penny connected to real life?
If you do it, yes it is. Pointless, perhaps, but then so much of real life is pointless!
What property of water allowes so many drops of water to stay on a penny?
adhesion
How much water does soil hold?
up to 12 inches of water. depends on type of soils some water is held so tight that the roots of plants can not grab the water so that they can photosynthesis............ thanks so much for looking at my answer!!! love you sexy

It's still woth a penny
How much is a 1828 penny worth?
An 1828 penny can be worth up to about $40.00. It is the large cent penny, so it is quite rare today.
How much of cold water can a person hold?
There is only so much water cold or hot that a person can drink and hold in their body at a time. For many people it is about 60 to 100 ounces before they have to use the restroom to relieve themselves.
How much is a US penny worth from the 1870s?
A penny is always worth a penny no matter what.
