How can u make water denser?

Question

Im trying to do this science fair project and I need to know what makes water denser!!! Will sugar or salt make it denser?

HELP!!

Answer 1

Adding salt to the water or freezing it

Answer 2

Salt for sure. Salt water from oil wells weighs about 11 pounds per gallon but pure water weighs less than 9 pounds per gallon. When I was a kid they showed people in my texts having a picnic on the water in the Great Salt lake. The picnic spread floated on top. Sugar would do the same.

Freezing would make it denser too.

Answer 3

SALT

Answer 4

ice makes water more dense because the hydrogen bonds traps the air.

i do not believe that salt or sugar effect the density but they effect the boiling point and freezing point

Answer 5

throw some chocolate milk in there

Answer 6

try this site and c if it helps

Answer 7

adding impurities ( such as sugar or salt) makes it more dense, this is why its easier for people to float in salt water.

If you want extra credit...

you can also make water or dense by cooling it. Or by adding hydrogen molecules (aka heavy water or H202)

After you added more info I have some things to add:

First off be careful a lot of wrong info in here. Ice is less dense than water, hence why it floats in your drink(or iceburgs) because it traps air.

If I were you I would try to experiment with changing the two things you have.  

What if the eggs are hard boiled?

What if you chill the water a lot (cold but not frozen).  

What if you heat the water as you add the salt so that it becomes supersaturated?

what if you heat the egg and put it in the cold water (remember heat rises)?

Find out the properties that effect density and see how you can modify them in your experiment.

Good luck!

Answer 8

Well, when you freeze water is becomes 10% larger. (or denser if you prefer)

Answer 9

Yes.

Dissolving salt in water will make it denser.

bye for now.

Answer 10

a lot of wrong answers. Ice has a lower density that water.

Salt will increase the density of the mixture slightly. As will sugar. But it's not the density of water that is changing, it's the density of the mixture going up because of the added salt or sugar.

If you really want eggs to float, leave them out until they go bad. The test for a spoiled egg is to see if it floats.

I don't think a good egg will float in salt water. But you can test that in less time then it took you to type this question. Add some salt to water and put an egg into it.

Answer 11

No. Water has a density of 1. If you want it to be pure H20 (sorry about the big 2) then you can't make it denser.  

Answer 12

LOTS OF BUBBLES FROM UNDER THE WATER

Answer 13

Im not sure, I know that salt lowers the freezing temperature for water, and also makes water boil faster. And I dont know anything about sugar in water except that its good for plants.  

Water is weird, its one of the only things that expands when if freezes.
