Hello,
Ice does have the same mass as water before it melts. You can (almost) never lose or gain mass without adding or
subtracting
mass from the system. Mass just can't appear or
disappear
from
nowhere
.
According in water the volume that ice occupies is greater than that of water due to the arrangements of the molecules of ice. This is why you would be led to think
there
is a change in mass.
However, according to this Law of conservation of mass, the number of particles in an ice cube and water are the same. Only the state has changed, not the mass.

∙ 14y agoAs per mass energy equivalence concept mass and energy are inter convertible. But here,the energy we supply to melt ice is not converted to mass, it is rather used to increase the potential energy of molecules and break the hydrogen bonds between them.
Mass energy interconversion takes place in nuclear reactions, not in physical or chemical reactions. Melting of ice just a physical reaction.
Ice floats on water so one may think ice had less mass and water has more mass, but actually ice contracts on melting so the volume of water produced is less than ice's original volume so the density of water is more. Since, water is denser than ice so ice floats on it.

Why don't floating ice cubes raise the water level when they melt?
cause whhen ice melts it turns to water that all i should have to say **The previous answer is nonsense. If the dough (or whatever other material you wish to use) is floating in a full cup of water with ice, as the ice melts the level of the cup WILL NOT RISE. Simple physics, ice is less dense than water. Density is equal to mass divided by volume or Density = Mass/Volume Therefore, differentiating between equal masses of water and ice, the melted ice will have LESS volume than the equal (mass) amount of water in the glass thereby having no effect on the overall volume of water in the glass..... to paraphrase the first answer-er ... 'duh'
Does the mass of ice reduce after melted to water?
What happens to the mass of ice as it melts into water? Nothing. The mass stays exactly the same. Mass can be defined as the amount of matter present in an object, and no matter is added to or taken away from ice as it changes into its liquid state, water. However, interestingly, the DENSITY (or the way the mass is distributed throughout the object, defined as mass per volume or g/mL) does change as ice becomes water. As ice melts to water, its density increases. Another way of looking at it is, as water freezes to ice, its density decreases. This is why ice floats on water! (If this weren't so, the worlds climate and environment would be drastically different -- think of the polar ice caps...) _______________________________________________________________________ But it is true that : ice weighs 0.92 g/mL and water is 1 g/mL so technically there is a difference Thank you George. Just to clarify a minor point, those values you gave aren't weight, but density. Ice doesn't "weigh" 0.92 g/mL, that value is its density. The density of ice is 0.92 g/mL The density of water is 1 g/mL Density is a measurement of the way an objects weight is distributed in a volume. When a block of ice with a certain mass melts into water, the mass of the water is EXACTLY the same. What changes is the volume occupied by the water when the ice melts. So, as far as weight, or mass, is concerned, there still is technically no difference.
Is ice dangerous?
No, dry ice is frozen carbondioxide. (CO2) If melted in water, most of it will evapourate to the athmosphere. If melted in water in a closed container, pressure will rise and water will become 'carbonized' = sparkling water!
What stays the same when ice melts?
Mass of water
How are dry valleys formed?
when melted water from the ice age erodes a valley but without the constant flow of water from the melting ice it dries up as there is not enough water to keep flowing through it, so it dries up but leaves the valley it has cut into the landscape. when melted water from the ice age erodes a valley but without the constant flow of water from the melting ice it dries up as there is not enough water to keep flowing through it, so it dries up but leaves the valley it has cut into the landscape.
Can you eat melted ice?
No, because melted ice is water - you drink water.
Why does melted ice boil?
Melted ice is liquid water and water boil.
If someone placed some ice cubes ina a beaker in a warm room the total mass of the ice cubes was 40g what mass of water is formed when all the ice has melted?
the mass does not change only the shape
What is a melted ice cap?
An ice cap is an ice mass that covers less than 50 000 km² of land area (usually covering a highland area), so a melted ice cap is literally just one that has melted, and the high volume of water causes floods.
What is melted glacier ice?
water
What is the water availability in Antarctica?
Water is abundant by melting glacial ice or by desalinating sea water.
What is the difference between the water from melted ice and the ice itself?
molecules from ice is more dense than water
How do Antarctic scientists get water?
drink the melted ice
Why does it take longer to heat up melted ice than regular tap water?
Because melted ice will still be a lot colder than the tap water.
What do you call ice that is melted into a liquid?
Water Water has three forms: solid = ice / liquid = water / gas = steam
How is water obtained in Antarctica?
Water is available from melted ice, or from desalinated sea water.
Will the mass of melted ice decrease?
No, but it will take up slightly less space after melting.
