Why a perspex block sinks in fresh water but will float in very salty water?
The difference in density between the perspex block and the water is what determines whether it sinks or floats. In fresh water, the density of the perspex block is greater than that of the water, causing it to sink. However, in very salty water, the increased density of the water allows the less dense perspex block to float.
How much of the water that evaporates from a salty ocean is fresh water?
Only about 10 of the water that evaporates from a salty ocean is fresh water.
Why should an object sink in salty water and float in fresh water?
The only possible reason for that would be that after the object floated for a while,the salt ate a hole in it, the water poured into it, and it stopped floating.If the object doesn't corrode, dissolve, or get water-logged, then it might float insalty water and sink in fresh water, because salty water is always more densethan either fresh or distilled water.
What type of water would a swimmer float more easily?
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!
Does eggs float better on salt water or fresh water?
Eggs will float better in saltwater because the salt makes the water denser, causing the egg to float more easily. In freshwater, the egg may sink or not float as readily due to the lower density of the water.

Do icebergs from the North or South Pole taste salty?
The surface of any iceberg will taste salty, because it floats in salt water. The interior ice, however, is frozen fresh water.
Do pieces of ice float in salt water?
I think that salty ice cube do float in water because ice bergs float it water and they're made of salty water. i think i depends on the density (Amount of salt) in the ice
