Buoyant force and water displacement

[mrneuro]

couple question regarding buyoancy and water displacment

1. so if you have a pond w/ ρ=1.2 and part of the water in that pond turns into ice will the level decrease increase stay the same? (i think it will stay the same)

2. same pond w/ a ρ=1.2 and you add ice cubes w/ a ρ= 1.2 the cubes should float (im assuming that ρ= 1.2 g/mL has the same characteristics of water) and the level should remain the same?

3. same pond but now you add ice cubes w/ a ρ=1.0 you put them in the level rises and they're only partially submerged...what happens does the level stay the same after it's done melting or does it increase?

4a same pond but now you add ice cube w/ ρ=1.2 and hold it under water will the level decrease after its done melting?

4b same pond but now you add ice cube w/ ρ=1.0 and hold it under water will the level also decrease b/c ice has a greater volume than liquid water?pretty much just wondering when will adding ice increase the level of water after it melts? and what effect do two objects with equal volumes but different densities (say p1 > p2) have on the same glass of water or pond?

1. The level of the pond will stay the same, as ice has the same buoyancy as liquid water. 2. The cubes should float and the level should remain the same.3. The level will increase when you add the cubes with a lower density, since the cubes are displacing more liquid water than it would if they had the same density. 4a. The level will decrease after it is done melting, since the ice has a greater volume than liquid water.4b. The level will also decrease, since the ice with the lower density is displacing more liquid water than it would if it had the same density.
