Because it is the same property, it doesn't change substance, it just changes form. If you took a cooked potato and mashed it, it would stay the same weight, you didn't change what it is, you just changed the form it took.

The ice doesn't lose or gain mass when it melts, it just changes state from a solid to a liquid.

What happens to the mass of 40g of i c e cubes when they melt?
Nothing. Ignoring evaporation, the mass stays the same as ice turns to water. It's a physical change, not a chemical.
Why when you put ice in a cup and then you put water in it to melt the ice the water level doesnt change?
This is because you are not changing the mass of the water, there are still the same amount of molecules in the cup, although more energized they still occupy [relatively] the same amount of room. I say relatively, because the molecules are slightly more spaces, due to the energy obtained with heat.
What are the two process which turn liquid into solid?
water change to steam ice melt to water
Does the density of objects change if you melt them?
As long as none of the water evaporates as the ice melts, the mass of water left over will be exactly the same as the mass of the ice cubes. the mass of ice is less than that of water ( that's why it floats ) therefore when it melts it takes up less space ( water expands when it freezes ) so the mass ( not the size ) is greater although the weight remains the same
Are phase changes in matter permanent?
No. Water freezing into ice is a good example of a "phase change". Ice can melt back into water, so we know that the phase change is not permanent!
Why doesnt temperature change when transferring from ice too water?
The thermal energy required to change state is taken from the environment; which in this case is the melt water.

What are two ways mass can change?
melt to a liquid and evaporate as a gas
How can you change a soild to a liquid?
How do you change ice to water? You melt it.

Do ice float in water?
yes, ice does float in water. it will eventually melt and change into water.
How do you melt a penny in coke?
it doesnt melt, but it gets very clean!
How a solid change into a liquid?
Many solids will change into liquids if you heat them, for instance most metals will melt when subjected to heat, ice will become water when heated, some plastics will melt, glass will melt, and most rocks will also melt.
What are the two process which turn liquid into solid?
water change to steam ice melt to water
Why might a very hot rock might not melt?
it might not melt if it doesnt have fluid in it
Does salt melt on cold mornings?
Salt doesnt melt, it is absorbed, and as for melting on cold mornings.... name something that does melt on a cold morning.----Salt will cause water ice to soften and melt unless the temperature is very cold (much colder than you're ever likely to see this side of the arctic circle). the salt itself doesn't melt; it converts the ice around it to water and dissolves in that water, allowing it to spread out and melt more ice.
Why doesnt the northern ice cap on Mars melt?
The temperature on Mars is too cold for water to exist in liquid form on its surface.
