Does water weight more when frozen or when in liquid?

Question

1 litter of water weights more in liquid or frozen solid?

Answer 1

If you have the same amount of liquid H2O and frozen H20, then the weight should be the same.

You have the same amount of mass in both cases, and weight is calculated by multiplying the downward force of gravity (9.8m/s2) X the mass of the object (in kg)

weight = mass X gravity

You have the same mass and the same gravity, so the weight will be the same.

Answer 2

Water weighs more as a liquid form, hence why ice floats.

But Ice takes up more space, hence it expanding

Answer 3

The weight will NOT change by cooling or warming a given mass of water.

The volume, and therefore the density WILL change.

Water has its greatest density at ~ +4°C.

Answer 4

Trick question.  If you take a liter of water a freeze it, it will weigh exactly as much as it did before, since you didn't add or remove any matter during the freezing process.  Ice is less dense than water, though, so a liter of ice would weigh less than a liter of water.

Answer 5

No! I saw a documentary called "Absolute Zero" and a scientist actually tried to see if frozen water weighed more than liquid water because he had a theory that cold (actual cold) was a particle. And that said particle was what made things colder. Since particles have weight if the frozen water weighed more than the liquid it would make his theory possible. But both weighed the same dissproving his theory.

Edit: It's a really cool documentary, maybe you wanna watch it, just search "absolute zero" after searching "www12.alluc" on google.
