If you were to replace the ocean with or mercury or oil, which works best for a boat's ability to float?. Thank you.
The answer to this question can be very simply understood.
The simple question is when things float at all?
Things float when their density (mass per unit volume) is less than the volume of the liquid they are in.
Bloat's float on water because their density is less than the water, boats may be heavy than a nail but because of there high volume their density goes down and they float.
Same is true for any other liquid if the boat is the same and liquid are different for example mercury and oil. Mercury (13.56 g/cm3) has more density than Oil (0.93 g/cm3). This means a high-density thing will easily float of mercury (Things float when their density (mass per unit volume) is less than the volume of the liquid they are in.) but the same thing will not float in oil.
Conclusion: if we were to replace the ocean with mercury or oil, mercury will work best for boat's floating ability because of its higher density than oil.
