Will once of liquid water weigh more than once if frozen into ice?

Question

Will once of liquid water weigh more than once if frozen into ice?

Answer 1

no....it's still an ounce

Answer 2

Yes, its mass (not weight, weight is dependent on the acceleration of gravity) is still the same. But the density will be lower in ice due to open crystal structure of ice.

Answer 3

nO , IT'LL STAY AN OUNCE IF U HAVE NOT ADDED ANY WATER OR ICE

Answer 4

Freeze an ounce of water then drop it into a glass with an ounce of liquid water....it floats eh?  (And no it doesn't need air bubbles frozen inside of it in order to float).

Answer 5

well unless you are freezing it by using nuclear isotopes then no mass leaves or enters the system and so its mass is the same, however as it freezes its density decrees so it will expand. this expansion could lead the ice to be slightly further away from the surface of the earth than when it was liquid and hence it will experience slightly less gravity and therefor will weigh less. but to be honest that's just nitpicking, the weight will stay the same, the difference is negligible  

Answer 6

Richard...an Nevah...

What you mean is the ice's NET force on Earth, will be less, due to a slightly larger Boyance force due to the atmosphere or water

However, it's WEIGHT is still the same... because weight is defined as:

W = mg

since m is constant.. and g is only depended on the separation of the object and the surface of the Earth, (not atmosphere or density or lifting due to boyancy in water),

The reason the ice floats in water is because the water offers an upward boyancy force, to negate some of the ice's weight.

So weight for both the liquid water and ice will be the same.

I am not familiar with the term 'fluid ounce' and I'm unsure if this question refers to 'fluid ounce'...

Answer 7

No, only the volume changes.

Answer 8

No the weight will be the same.  The density and therefore the volume of the ice will be different from the water.  Water expands when frozen becoming less dense and is why Ice floats on water.

Answer 9

a fluid ounce is a measure of volume and liquid water at 0 deg c is more dense than ice at 0 deg c and so one fluid ounce of water at zero deg c will weigh more than one fluid ounce of ice at zero deg c.
