When the Penny Drops was created in 2010.
A Penny..the other day I found a penny from the 20s. Its still a penny not much as changed.
...If you can read the date on the penny, it is not an unstamped penny.
A penny.
The Penny ended in 2006.
Lincoln is on this penny.
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.
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?
The penny's state of corrosion.
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.
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 can a penny hold? topic: crazy 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.
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.
