density - Why are most hydrocarbons less dense than water?

Web1) Oil has a density less than water, so it just sits there on the top, not spreading out into the more dense water below. 2) Oil is very nonpolar, meaning that a polar molecule like water doesn't get attracted to it. Oil is … Web31 rows · May 6, 2024 · Density is a measure of the amount of mass contained in a unit of volume.

Comparison of Water with Other Liquids

WebWater requires more energy per gram of liquid to change its temperature. Because the input of the heat from the hotplate and the microwave is the same across trials, and water takes longer to heat up to a given … WebThe formula F b = Δ V ρ g hold whether you submerge an object or not. So for a completely submerged object the buoyant is stronger in dense liquids because Δ V is the same. If the buoyant force is bigger than the weight of the object, the object floats. It will move upwards until the forces are balanced: Δ V ρ g = m g. WebJan 9, 2012 · 7,253. 63. brewnog said: Oil is usually more viscous (not dense) than water, perhaps this is the source of your confusion. Humm.. viscousity has nothing to do with floating, density has everything to do with floating. Oil floats on water, therefore oil is less dense then water. Feb 1, 2005. #7. tlcf 税金
