Question

If you have a glass with liquid in it, any liquid and there are ice cubes in it, what will happen to the water level as the ice cubes melt? In other words in a glass with water and ice in it will the water level raise, or lower, or stay the same as the ice cubes melt? If you have the answer than prove it, give a link to a website or explain it, dont just say the answer.

would it really be the same because as the ice melts the air trapped in the cube is released in the air?

Answer 1

Typically, the water level will fall, but only slightly. Water expands when it freezes, so it is larger as a solid than as a liquid. Also, air bubbles tend to get trapped in the ice, so there's less water than there is ice.

Answer 2

It will stay the same. There isn't air in the ice, ice floats because water's molecular structure expands when frozen. The volume that the ice previously displaced water will be exactly the same amount of liquid created from the ice melting.

Answer 3

As the ice melts, the level of water in the container will lower. This is because unlike any other molecule, as water freezes, it expands. The molecules in the lattice structure of ice are spread apart, that is they are not close together to form the solid state of water. So, when ice melts, the molecules come closer together (very different from normal) and therefore, the level of water in the container will lower.

Answer 4

This is very simple question and I am surprised to see all the funny answers here.
First understand these points.
1. Density = mass / vol.
2. water becomes less dense when it freezes, that means, it grows bigger but the total mass remains the same and that's why ice floats on water
3. Law of buoyancy says "weight of floating body = weight of water displaced"

Now imagine you have 1 litre of water in a bottle with markings on every 0.1litre. You put an ice cube in it and suppose water level increases to 1.1 litre.
according to point 3, weight of 0.1 litre of water = wt. of ice cube
Let the ice melt
now, wt. of 0.1 L of water = wt. of molten ice
but volume of 0.1L of water = vol. of molten ice, because molten ice is water
therefore water level remains at 1.1 L
I think you got the answer now.
But if the liquid in the bottle is not water, using the same principles as above, you can find that,
1. final level increases for a liquid denser than water
2. final level decreases for a liquid less dense than water

Answer 5

The water level stays the same. The volume of water displaced by the ice depends on the mass of the ice, which does not change when it melts. Try it!
Postscript: the liquid has to be water, or something of density very near to water for this to be true. Kool-Aid would work; alcohol wouldn't.

Answer 6

The level of liquid in a glass sligthly rise because in any matter its temperature is directly proportional to its volume.In this case its the melting of the ice then the volume of the ice will increase.

Answer 7

The density of the ice cubes increases, as they turn back in to a liquid. The water molicules are spread farther apart when they are solid. Density changes there for the mas/volume changes. (D=M/V) Leading to a very slight decrease in the level of the liquid.

Answer 8

there's nothin to prove or show its straight forward, when u put ice cubes in a glass of water the displacement caused by the ice cubes is counterbalanced when the ice cubes melt. in other words at vol 3 cubic inches and u put ice cubes and rises to a volume 4 icubic inches the one cubic inch difference is equal to the volume of the ice. so the level remains at 4 cubic inch.

Answer 9

When ice or anything else floats in water, the weight of the water it displaces is equal to the floating object's weight. So when it melts, the water level will not change.

Answer 10

raise. I suppose because the mass will increase as the ice cubes melt.
