How can a penny float?
A penny will not float in water, mainly because it is denser than water. When the penny is placed in water, it displaces a volume of water equal to its own volume. Since the penny weighs more than the water it displaces, it will sink.So, in order for the penny to float, you must find a liquid that is denser than solid copper -- or whatever metal or alloy a penny is made of. Mercury -- which is a liquid at room temperature -- is denser than copper. Hence, a penny will float in mercury.Possibly surface tension may allow it to float.
Why will a penny float in cooking oil?
it will float bc the penny is so light that it should float.
What is denser a penny or a paperclip?
A penny is denser than a paperclip. Pennies are made of copper and have a higher density compared to paperclips, which are typically made of steel. Density is a measure of mass per unit volume, so the penny is denser due to its material composition.
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.
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.
Why does a boat float in salt water but not a penny?
penny's aren't tall enough!
Which coins decompose faster in fresh water?
Maybe a penny cause it's least denser. But otherwise I don't know. Maybe a penny cause it's least denser. But otherwise I don't know.
Why doesn't a penny float in the water?
because you're fat
Can you make a penny float?
No, pennies are too heavy to float on water due to their density. However, you can create the illusion of a floating penny by carefully balancing it on the surface tension of the water.
Does a new penny float in hcl?
when the penny is reacted with HCl, there must be somesort of area where the copper on the outside of the penny is removed so that the HCl can react with the zinc inside because HCl does not react with copper. Once the HCl reacts with the Zn inside, it will dissapear and therefore become less dense then the ZnCl2 that is formed which causes the penny to float
What liquid will rust a penny and a paperclip the fastest?
oil
Is a gold penny chemical or physical?
It's chemical because you have to heat a liquid until it's super hot then you put the penny's in a cooler liquid and then it changes color.
