Density is not a visual quality. But we can infer information about density by observing. For example moist air is lighter than dry air - that is why the clouds condense at higher altitudes, not at ground level. {Explanation - H2O has an molecular mass of 28; O2 has an molecular mass of 32; N2 has an molecular mass of 34. Hence H2O vapour is lighter than O2 or N2.}
mole is short for molecular. they are basically one in the same. the molecular mass is in amus, the average mass unit, and the mole is a number that converts amus to grams. a mole is the amount of particle in 12 grams of carbon-12, best explained by avagadros number: 6.022*10^23. this is to say molecular mass is the mass of a molecule, and the molar mass is the amount of moles. so there would be 10 moles in 10 grams of Hydrogen. and a molecule of hydrogen, H2, would be 2.014 amu.
The changes occuring in molecular attraction as water goes from a solid to a liquid is that the bonds between the molecules weaken and the molecules move further away from each other. Once they become a gas, their bonds break and the molecules float freely around.
i have read water has maximum density at temprature of 4 degree celsius...so water vapour is not most dense form of water.
CAVITATION is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. where SUPERCAVITATION IS THE CONTROLLED FORM OF CAVITATION WHICH HELP US TO attain more underwater speed
density is mass per unit volume, meaning that as mass increases ,the density increases. Unlike volume, as it increases the density decreases.
The molecular mass of water vapour is 18.01528

The vapour density of equimolar mixture of methane and oxygen is 0.0831 lbm/ft3.
There is no similarity between vapor density and firefighting - one is a measure of the density of a gas or vapour relative to another (often Hydrogen or air) and the other is heroic job.
With increase in temperature , the density of fluids decreases and their vapour pressure increases. There's no direct relationship for temp-density of HYdrocarbons. But temperature and density are inversely proportional and the constant of proportionality varies from fluid to fluid. For hydrocarbons that constant can be calculated keeping in mind its VP, boiling point at ambient conditions and its constituents.
Because ice is solid and has a heavier weight that cause it to have higher density and as for water vapour, it is gaseous and has lower density due to not having any weight.
A parachor is a constant for a liquid that relates the surface tension to the molecular volume. The formula is P = y^(1/4)(M/d) where y is the 4th root of the surface tension. M is the molar mass, and d is the density.
Density is the quantity of matter present in a unit of volume. It is denoted by D. The SI unit for density is kg/m^3. The density of acetone vapour is 0.86 kg/m^3 at 98.5 degree Celsius.
