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.

Would the density of white oak sink or float if it is placed in water?
The density of the wood would not be affected by being placed in water. However, the wood itself, with a density of about 0.77 gm/cm3 , would float.
Does chloroform float or sink in water?

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.
Will a magnet float or sink?
A magnet would typically sink in water as it is denser than water and does not have the buoyancy to float.
Would gold sink or float in water?
Gold is a very dense metal, so it would sink in water rather than float.

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.

Would a penny sink in water?
Yes
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.
Would a cube that's 50 gram sink or float in water?
it would sink
Would Blocks sink or float?
Blocks made of materials like wood or plastic would typically float in water, while blocks made of materials like metal or concrete would sink. The density and composition of the block determine whether it will sink or float in water.
Do clothes float or sink?
