NO. Water has a density greater than gasoline, but gasoline, octane anyway, has a greater molecular mass than water molecules.
When water freezes, it expands and becomes less dense, causing it to float. This is because the molecular structure of ice forms a crystalline lattice that takes up more space than liquid water molecules. Therefore, frozen water (ice) is lighter than liquid water, which is why ice floats on water.
Cracking breaks down larger hydrocarbon molecules in crude oil into smaller molecules under high temperature and pressure. This process breaks chemical bonds in the molecules, causing them to fragment into lighter hydrocarbons, including gases like methane, ethane, propane, and butane.
Oil and water do not mix because they are composed of molecules with different polarities. Oil molecules are non-polar, meaning they do not have a charged region, while water molecules are polar, with a positive and negative end. This difference in polarity prevents the molecules from forming stable bonds with each other, causing them to separate into distinct layers.
yes. Because methane is lighter than any liquid, bubbles of methane will always rise in solution.
It is possible to separate hydrocarbons in crude oil by distillation because different hydrocarbons have different boiling points. This allows for the fractional distillation process, where crude oil is heated and the vapors are condensed at different temperatures to isolate various hydrocarbon fractions with similar boiling points.
Well, if in a gas you have a mixture of heavier and lighter particles (atoms or molecules, really), the lighter particles will tend to move faster than the heavier particles. The general tendency is for any such particle to have the same energy (mainly kinetic energy). Similarly, in a liquid solution, lighter particles will tend to move faster.
A liquid can be heavier than a solid due to differences in density and packing of molecules. In some cases, liquids have a higher density than solids of the same material, causing them to be heavier. Additionally, the ability of molecules in a liquid to move around freely and take up more space can contribute to its weight.
in relation to solids or liquids in liquids: Density. A lighter density compound/liquid will float in a heavier density liquid
Depends on the liquid because all liquids have different densities making them lighter or heavier
The fuel in a typical cigarette lighter is a liquid, such as butane or lighter fluid. When the lighter is ignited, the liquid fuel vaporizes and burns to produce a flame.
A hydrometer sinks more in lighter liquids because it is designed to float higher in liquids with lower density. The buoyant force acting on the hydrometer is greater in lighter liquids, causing it to sink deeper. As a result, the reading on the hydrometer will be lower in lighter liquids compared to heavier ones.

During evaporation, molecules of a liquid gain enough kinetic energy to break free from the liquid surface and escape into the gas phase as water vapor. This process involves individual molecules transitioning from the liquid phase to the gas phase without the liquid boiling.
Oil and water do not mix because they are composed of molecules with different polarities. Oil molecules are non-polar, meaning they do not have a charged region, while water molecules are polar, with a positive and negative end.

Yes, weight and density play a role in determining whether an object will break the surface tension of a liquid. Objects that are heavier or denser are more likely to break the surface tension, as they can exert a greater force on the liquid molecules. Lighter or less dense objects may not have sufficient force to break the surface tension of the liquid.
Because they have a lighter density than water. However, in some other liquid a poppy seed might sink because of having heavier density than that liquid.
Take a litre of water and a litre of steam. They are both H20. The heavier one must contain more molecules, and its molecules must be more "closely packed". So, does the liquid or the cas have "particles more spread out"?
