What is the buoyancy of 0.27kg aluminum in water, alcohol and mercury? Density: Aluminum 2700, mercury 13600 g = 10N
What is the buoyancy of 0.27kg aluminum in water, alcohol and mercury? Density: Aluminum 2700, mercury 13600 g = 10N
(1) Aluminum block sinking in alcohol
F floating = ρ liquid GV discharge
=ρ liquid g (M Al / ρ al)
=1000*10*0.27/2700
=1N
（2）
In mercury, aluminum floats (the density of mercury is higher than that of aluminum)
F = g aluminum
=0.27*10
=2.7N
