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.
Nope. Stick a penny in some coke or pepsi (Coke preferred) and wait like an hour or two (im not sure maybe a day if you don't see any progress) and voila! A really clean penny.
sit the glass of water on the penny
a penny sinks in water because the penny is denser than water,so even if the penny is on the moon,its density is still larger than water,and the penny would still sink.
NO magnets arent attracted to copper
Stick a penny next to the tip and push down on the contact spring. The needle should stick out the same as the width of the penny
Penny. Put the ball, duck and penny in water. Only the penny sinks.
no. a penny can not float on water. only a feather can do that, i think. sorry!
It depends on what you used to put the water on the penny and how far your holding the tool in the air away from the penny
A penny sinks.
No. No genuine US coin other than the 1943 steel penny will stick to a magnet. If you have a US coin that sticks to a magnet other than the steel penny, it is a counterfeit.
A penny would sink in a river because a penny is made mostly of zinc, which is heavier than water. Because the penny is heavier than water, it sinks.
regular water will make a penny rust.. it takes a while though
I think that water can hold the penny more than honey
Back in my day, you could get a licorice stick for a penny.
No. Copper is not attracted to a magnet.
Other than the DATE it will stick to a magnet.
A penny as everyone I'm sure knows cannot float in regular water. As for salt water a penny should in theory not be able to becase the regular pennys bouancy is not great enough to support the weight of the penny regardless of the salt to water ratio. A penny is too dense to be able to float in salt water, regardless of the salinity of the solution.
No. Copper is not a magnetic metal. But you knew that already because you tried using a magnet on an ordinary penny, correct?
That is due to the property of cohesion - a substance's ability to stick to itself. Water is very cohesive, so when one part of a droplet moves, so does the rest.
Nothing necessarily happens to the penny.
why dose a penny rust faster in salt water than in vinegar
A penny is a solid, flat object and does not hold much water at all.
