good question..
first i want to say why a body floats in any liquid?the answer is it only due to the density.If the density if the body is less than that of the liquid then the body floats in that particular liquid.there is nothing to do with the weight.Yes we can say that the density is directly propertional to the mass but yes that is also inversely propertional to the volume.the relationship is given as ,
density=(mass)/(volume)
now come to the ice and water.as the density of the ice is less than that of the water so the ice floats in the water.
now a question arises how i know that the density of ice is less that that of the water?we know if the same amount of the water coverts to the solid form(ice) then the volume increases but the mass is same so acording to the relation the density decreases.
I think u got the answer.
- Because of the lower density in ice, pressure is altered (P=pgh) where height is the depth of water. Because the pressure is greater at the bottom of the ice than the top (greater h), an unbalanced, upwards force, a.k.a buoyancy, is exerted. Therefore ice floats on water

Does a glass float or sink in water?
It depends on the shape of the fork and the material from which it is made. Most non-metal (wood, plastic) forks will float. Metal forks will sink unless they are shaped to have a large enough surface area on the bottom.
Why do some objects float or sink in water?
It depends on the density of an object. If the density is higher than the density of the liquid, the it sink. If it's less, it floats.
Why does some food float and some food not?
Whether an object floats or not depends on its density. Density is the amount of mass in a volume, or mass divided by volume. If and object's density is less than that of water, it will float in water, and if an objects density is higher than that of water, it will sink in water. raw material (fishballs will sink down);but it will floats when it is cook. why
What object floats in the middle of water?
what object will not sink or float but will stay suspended in the middle of water
Why is it incorrect to say that heavy objects sink in water?
It is incorrect to say that heavy objects sink in water because... A big slab of wood is heavy, right? Wood floats. For one example.
Does glass bangle sink or floats in water?
Glass bangles are denser than water, so they typically sink when placed in water. This is because the density of the glass is higher than that of the water, causing it to displace less water and sink.
Does ice sink to the bottom of water because it is more dense than water?
First of all... ice floats in water.
What force causes a rock to sink to the bottom of a glass of water?
Gravity
Why would a small pebble sink and an oil tanker floats?
Because a pebble is denser than water thus making it sink oil is not denser than water. you can test this by pouring some oil in a glass of water it floats on top of the water it doesn't sink it is the same theory with the oil tanker in the sea.
Which force causes a marble to sink to the bottom of a glass of water?
The force of gravity is what causes the marble to sink to the bottom of the glass of water. Gravity pulls the marble downward towards the center of the Earth, overcoming the buoyant force exerted by the water.
Does a glass float or sink in water?
It depends on the shape of the fork and the material from which it is made. Most non-metal (wood, plastic) forks will float. Metal forks will sink unless they are shaped to have a large enough surface area on the bottom.
What force causes a marble to sink to the bottom of a glass of water?
The force of gravity pulls the marble downward, causing it to sink to the bottom of the glass of water. The weight of the marble exceeds the buoyant force acting on it, which results in its downward motion through the water.
Does silk float or sink in water?
It floats, but after a while silk will sink.
Why ice floats on water and does not sink?
Ice is less dense than water, so it floats.
Will wax sink in water?
No, it floats. Try it.
Will Wax float or sink in water and why?
floats
Does ice float or sink in water why?
it floats beacause there is water in it
