Human waste is heavier than water, so it sinks to the bottom. Then, the water is pumped through a pipe leaving the heavier substances behind, and the waste is disposed of.Hope this helps. :)
If an object placed in water sinks - then it has a density greater than water.
dehydration occurs when water loss is greater than water intake.
Yes. :D
A density greater than that of water (which varies with temperature).
iron is 7.9 times greater than water
Water has a greater density than ice.
what is the effect of placing an object with a greater density than water in a bucket of water
Because of the weight of the water above.
No, antimony sinks in water because its density is greater than that of water.
why is it important not to pour things other than waste, water down the drain.
Because "black water" means "water that we can't use", and "grey water" means "water that we can use".The definition of grey water is that it is waste water that is safe to use (other than for drinking) without treatment. The definition of black water is that it is waste water that requires treatment before re-use. If you have water that you can use, then by definition it isn't black. If you have black water, then whatever reason that it is black is the reason that you can't use it.
