Is it true that it's easier for a human body to float and salt-water than fresh water? And the same for objects in general?

>>	Anonymous Sat Mar 26 05:26:38 2011 No.2775478 salt water is more dense than fresh water, therefore the buoyant force applied due to your body displacing the salt water is stronger than the same situation with fresh water. yes and yes

yes op this is true.

in order to float, you have to weigh less than the volume of liquid you displace (shove out of the way, occupy, whatever)

so the same object (human body, whatever) will occupy the same volume of salt or fresh water, BUT the salt water will weigh more (due to the salt, duh).

thus it is easier to weigh less than the salt water you displace, and therefore float. voila!
