"Density" water is heaver than ice so the ice floats on it.
Added:
There is a Calvin and Hobbes cartoon in which Calvin poses the question to Dad:
"Why does ice float?"
Dad responds:
"Because it's cold. Ice wants to get warm, so it goes to the top of liquids in order to be nearer to the Sun."
See the related question below for an in-depth explanation.

b. lower freezing point A 0.5 M solution of potassium chloride will have a lower freezing point compared to pure water due to the presence of solute particles which disrupt the formation of ice crystals.
about 90%.
Ice has a lower density than water, so the same mass of ice will occupy more space compared to water. This is because the molecular arrangement in ice forms a lattice structure that makes it less compact, resulting in a greater volume for the same mass.
Salt lowers the freezing point of water, which means that when salt is added to ice, it causes the ice to melt faster. The process of the salt dissolving into the liquid water creates a brine solution with a lower freezing point than pure water, allowing the ice to melt at a lower temperature.
Compared to water, ice has a lower density, which allows it to float. This is because the molecules in ice are arranged in a way that creates open spaces, making it less dense than liquid water.
Water is a substance that is less dense as a solid (ice) compared to its liquid form. This is due to the unique structure of water molecules in ice, which causes them to form a lattice structure that takes up more space and results in a lower density compared to liquid water.
Yes, in ice, water molecules are in a more organized structure compared to when they are in liquid form. This results in a hexagonal lattice arrangement in ice, causing the molecules to be more spread out and creating a lower density compared to liquid water.
The refractive index of a material is related to how light propagates through it. Ice has a lower refractive index than water because its molecular structure is less dense and more sparse compared to water. This difference in molecular arrangement affects how light interacts with the substance, leading to a lower refractive index in ice compared to water.
The physical property of water that causes ice to float is its lower density compared to liquid water; ice has a density of about 0.92 g/cm³, while liquid water has a density of approximately 1.00 g/cm³. This lower density allows ice to remain buoyant in water. In contrast, many alcohols, such as ethanol, have a lower density than ice, which causes ice to sink when placed in alcohol.
Yes, ice will still float in salt water. However, the presence of the salt increases the water's density, requiring a slightly lower temperature for the ice to float compared to freshwater.
Yes, the temperature of dry ice in alcohol is typically much lower than that of ice water. Dry ice, which is solid carbon dioxide, sublimates at -78.5 degrees Celsius (-109.3 degrees Fahrenheit), while ice water remains at around 0 degrees Celsius (32 degrees Fahrenheit) when it is in equilibrium with melting ice. Therefore, dry ice in alcohol will have a significantly lower temperature compared to ice water.
100g of water is equal to 100g of ice in terms of weight, since they both have the same mass. However, the volume of the ice may be slightly larger due to the lower density of ice compared to water.
A sea water ice cube would melt faster than a normal ice cube because sea water has a lower freezing point due to the presence of salt. This means that it would require less heat energy to melt the sea water ice cube compared to a normal ice cube.

Ice water has a lower temperature than ice. Ice water is a mixture of ice and water at the temperature of 0 degrees Celsius, while ice is held at 0 degrees Celsius until it melts and transitions into water.
No. The temperature of dry ice is far lower than that of ice water.
