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.
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?
Water molecules stick together because of the electrical charges in the water create a bond.

"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.
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.
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.
how many drops of water can a penny hold? topic: crazy penny........
adhesion
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?

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.

The surface tension of water allows many drops to sit on a penny without spilling over the sides. The cohesive forces between water molecules create a strong bond, which enables the water to form a dome-like shape on the penny. This dome shape prevents the water from overflowing.
Cohesion is the attraction between water molecules that allows them to stick together. This cohesion enables the water drops to pile up on top of each other on the head side of a penny without spilling over the edge. The surface tension created by cohesion allows the drops to form a dome shape on the penny before spilling.
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.
