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.

ā 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.

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.
Why don't floating ice cubes raise the water level when they melt?
Floating ice displaces its weight in water, so when it melts, it simply fills the space it previously occupied without adding any additional volume to the water. This is due to Archimedes' principle that states an object partially or fully submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.
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!
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.
What stays the same when ice melts?
Mass of water
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 the water availability in Antarctica?
Water is abundant by melting glacial ice or by desalinating sea water.
What is melted glacier ice?
water
How do Antarctic scientists get water?
drink the melted ice
What is the difference between the water from melted ice and the ice itself?
The water from melted ice is in liquid form, while ice itself is in solid form. The water molecules in liquid water have more energy and are able to move more freely compared to the tightly packed ice molecules.
Does frozen water increase in size when melted?
Yes, frozen water (ice) is less dense than liquid water, so it actually increases in size when melted. This is why ice cubes float in liquid water.
What do you call ice that is melted into a liquid?
Water Water has three forms: solid = ice / liquid = water / gas = steam
How many grams of liquid water are produced when 119 grams of ice melt?
119 grams of ice would produce 119 grams of liquid water when melted because the mass remains the same during a phase change.
How many grams of ice can be melted with 145 grams of 45 degree C H2O?
To calculate how many grams of ice can be melted by 145 grams of water at 45Ā°C, you first need to determine how much heat is required to cool the water to 0Ā°C and then how much heat is needed to melt the ice at 0Ā°C. Use the specific heat capacity of water (4.18 J/gĀ°C) and the heat of fusion of ice (334 J/g) in your calculations. The final result will be the mass of ice melted.
