Does water weigh the same when it turns into ice?

Answer 1

It becomes less dense when it freezes, i.e. you will see tiny air bubbles in the ice after it freezes. Go look at some ice in the freezer! You will see the tiny bubbles...in your ice...THIS is why ice floats. The mass is unchanged.

Answer 2

Yes, when it turns to ice it simply changes in its structure. The density is less than that of water, but when it turns to ice it merely changes state, it doesn't lose mass. The weight of an object is w=mg (w= weight, m= mass, g= force of gravity).

So since the water may change state and turn to ice and float on water, it won't weigh less because it's not as dense as water because when the molecules align up with it's phase change from liquid to solid it creates molecular hollow areas.

Much like <> only picture it with each > lined up with each other on all four sides like that and it'll be similar to a bunch of tennis balls filling a void, you'll have a lot of hollow areas in them which means that they won't be as dense, but they'll have the same mass.

Answer 3

Ice at 0°C is Sublimating at a decrease fee than the water is Evaporating on an identical temperature The Ice might have an exceptionally slightly greater mass than the water it produces. The ice is soaking up a smaller volume of warmth capacity (Latent warmth of Fusion of 80cal/g) than the water (Latent warmth of Evaporation of 540cal/g). for this reason greater mass of water would be misplaced as vapour than the ice. Mass is neither created nor destroyed however the version in evaporation expenses will produce the above very gentle mass difference interior the quantity misplaced in forming vapour.

Answer 4

the mass of water if conserved in all situations.
this is the first law of thermodynamics

however the density of water changes when it freezes

this happens because the water forms a crystal structure with atomic sized empty spaces (whereas water molecules in liquid state are more closely packed)

if you have 1 cubic meter of ice vs 1 cubic meter of water
the water will be heavier because the density is higher.
(Density Units are Mass/Volume)

Answer 5

Yes, they have the same weight but different volumes because of the empty space trapped in the crystal structure of the ice.

Answer 6

Yes, but because of crystallization its volume increases and as a consequence its density will decrease. That's why ice floats on water.

Answer 7

For each gram of water at 0 C transforming into ice at 0 C the mass *decreases* by

[(3.347x10^9 ergs)/(3x10^10 cm/sec)^2] grams.

80 cal/gm heat of fusion and E = mc^2.

Answer 8

Not per unit volume (density) but a pound of water will make a pound of ice.

Answer 9

Yes - the mass (weight) doesn't change, but the volume does - it expands as the molecules rearrange themselves.
