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.

∙ 13y agoit would depend on the density of the liquid and the penny. if the penny is lighter then the liquid in density, then it will float. if it is heaver in density then it will sink

One example might be Mercury. At a density of 13.5 g cm-3 it would float a copper penny which is only 8.9 g cm-3. HOWEVER: DO NOT TRY THIS, because mercury is a significant poison, and can be directly absorbed into the skin.

∙ 14y agoa 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.

does Arsenic float or sink
Would a quarter float in water?
It will sink in water, but it will float in mercury. Depends on what the liquid is.
Does copper wire sink or float?
A short piece may be supported by the surface tension of water, but a coil of copper wire would sink.
Does a rubber band float?
Yes and no. Rubber bands can float and sink in water. They will float on the water for awhile and then will sink. But not all the time the rubber bands will float on the water for awhile. Sometimes it will immediately sink.
Would a skinny man float in water?
no he would most likely sink
Does Anorthite sink or float in water?
It will float. Its a rock. It actually depends on how much water you have, if you you tried float it in the ocean, it would obviously sink. But if you tried to float it on a gladd or bowl or water, it would float,
Why does a penny sink in water?
water has a density of 1. For something to float, the density of the object would have to be under 1, and to sink, it must be over 1. If it is exactly 1, then the object will remain suspended in the water. A penny has a density of over 1, so it sinks in water.
Would a human finger sink or float?

Marble has a density of 2.05 would it float or sink in water?
sink
Do ceramic float or sink?
a solid ceramic object would sink. however, if the object is displacing enough water proportional to it's weight, then it will float. If you put an empty glass bowl in the water, it will float; but if you allow water in, it will sink. This applies to ceramics.
Will a marker float or sink in water?
I have a marker which float in water.
Why would a penny sink in a river?
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.
