Air is less dense because the particles are mainly of lower molecular mass with similar volume, thus having an inherently lower density, and also because air is free to expand (as it is a gas) where water is liquid and so cannot expand or contract to any major degree.
Ice floats in water because it is less dense than water. A wooden boat floats on water because it is less dense than water. A balloon filled with helium gas floats in the air because it is less dense than the surrounding air. A cork floating in water floats because it is less dense than water. A rock sinks in water because it is more dense than water.
Yes, less dense objects float in water because they are lighter than the water they displace.
Ice is less dense than water because when water freezes and turns into ice, the molecules arrange themselves in a way that creates empty spaces between them, making ice less compact and therefore less dense than liquid water.
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
An eraser floats because it is less dense than water. The air trapped inside the eraser adds buoyancy, allowing it to float on the surface of the water.
Yes. Anything that is less dense than water will float on water.
Dense
No, lithium is less dense than water, so it will float on the surface of water.
The structure of frozen water (ice) is less dense than the random arrangement of the water molecules in liquid water, thus ice floats because water becomes less dense when it is frozen. Because of buoyancy forces, an object placed in a liquid will float if it is less dense than the liquid and sink if it is more dense.
Water at 0 is less dense than water at 4 because at the 0 the volume is larger than at 4.
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense

Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Yes, less dense objects float in water because they are lighter than the water they displace.
Ice is less dense than water
Ice is less dense than water due to hydrogen bonding. When water molecules freeze into ice, the hydrogen bonds hold the molecules in a more spaced-out, lattice-like structure, causing ice to be less dense than liquid water.
Ice is less dense than water because of the presence of hydrogen bonds.
