Water can fill the bottom of a glass because it flows easily and takes the shape of its container. Ice, on the other hand, is a solid with a fixed shape and volume, so it cannot fill the bottom of a glass. When water freezes into ice, it expands and retains its shape rather than conforming to the shape of the glass.
A glass of ice water is an example of a physical change, where water changes from a liquid to a solid state as it freezes. This change is reversible, as the ice can melt back into water.
When you stir the glass again after an hour, the sugar that settled at the bottom is likely to dissolve into the water due to the stirring action. The sugar particles will mix with the water more evenly and distribute throughout the solution.
Pick an answer: a) For both glasses, the water is about the same temperature, say just above 32F. Then the glass without ice has the most water by mass. b) The glass with only water is quite hot, say just below boiling. The glass with water and ice cubes is just about at 32F and the volume of ice is very small (less than 2%). The the glass with water and ice could have more water by mass. c) By definition, water refers to H2O in its solid form. By definition, ice refers to H2O in its solid form. So, "by definition", the half full glass with ice will always have less water by volume.
The ice cube melts in a glass of water because heat is transferred from the surrounding water to the ice cube, causing the ice to absorb energy and increase in temperature, eventually melting into water. This process is known as heat transfer through conduction.
When an ice cube is placed in a glass of alcohol, it tends to float either at the top or bottom depending on the relative density. Ice is less dense than alcohol, so it typically floats at the top of the glass. However, if the ice contains air bubbles or impurities, it may sink to the bottom due to reduced buoyancy.
Ice is less dense than water and therefore floats on water so when the glass has water in it the ice will always stay above the water.

By Laura. J. Duthie xx ------- If you do that, the penny will sink to the bottom. To make it look like the penny is suspended in the cube, do this: Fill a space in the ice cube tray (glass, whatever) half full of water, put it in the freezer. In an hour or so it will begin to freeze; it will get a crispy layer of ice on top. Put the penny on this layer, fill with COLD water (hot will melt the forming ice). Put it back in the freezer. - Kate_mc ------
1 lime 1 tsp sugar Water Ice cubes Measure the sugar, and dissolve in 1tsp boiling water. Pour into a glass. Add the lime, and fill up the rest of the glass with water, and drop in the ice cubes, but they are not really needed.

A glass of ice water is an example of a physical change, where water changes from a liquid to a solid state as it freezes. This change is reversible, as the ice can melt back into water.
The temperature will be the same.
The water level will decrease slightly when the ice cube melts, but the overall volume will remain constant. The melted ice will just fill the space that the ice cube previously occupied, so the glass will not overflow.
Ice tends to sink in alcohol due to differences in density. Alcohol is less dense than water, causing ice, which is denser than both alcohol and water, to sink to the bottom. This phenomenon is known as "alcohol stratification."
You can generally just fill the bottle a quarter of water and put in enough dry ice chunks to fill the bottom of the container; I'll say about 6 normal sized chunks for a 2-liter bomb.
Try putting hot water in the top pan while putting the bottom of the bottom pan in ice water. Wiggle. FriPilot
If he glass was full and you put ice cubes in it would overflow strait away.
