Heavier is an inappropriate word. Water is denserthan alcohol; it is not heavier. In your question, you should have written greater: Why is the density of water greater than the density of alcohol? Remember, density is defined as mass per unit volume. Examples are pounds per cubic foot (lb/ft3), kiolgrams per cubic meter (kg/m3), and milligrams per milliliter (mg/ml). You could say that water is heavier per unit volume than alcohol. That is the same as saying water is denser than alcohol. Think of it another way: Although water is denser than alcohol, a gallon of alcohol is heavier than a teaspoon of water. In other words, to determine which is heavier, you must first know how much you're starting with. Now, to answer your question! Water is denser than alcohol because the space between water molecules is less than the space between alcohol molecules. Hence, there is more matter per unit volume of water than per unit volume of alcohol. Since a unit volume of water contains more matter than an identical volume of alcohol, its denisty is greater.
Simply put, this is because the inter-molecular forces in water are stronger than those in ethanol. While both compounds are polar, water is smaller so the molecules can get closer together than ethanol can. The carbon junk in ethanol is quite a lot larger than the polar part, so it basically takes up space, preventing large numbers of polar regions from congregating.
Water has a density of 1000 kg/m3. The density of ethanol is 785.
Twins PWN the AL Central!!!
yes the density of water at 20 degrees centigrade is .0998 g/cm cubed
the density of ethanol is 0.789 g/cm cubed
Liquid alcohol is less dense than liquid water.
water has more density as more minerals can dissolve in water than ice
Water is denser than alcohol.
No
yes
yes
Between Xylene and Trichloroethane I think the Trichloroethane is the denser of the two. When water and trichloroethane are mixed, regardless of the quantity of water, trichlorothane is consistently denser then water. On the other hand when you mix xylene and water, water is the more dense liquid. It's my conclusion that since trichloroethane is denser than water and water is denser then xylene, then the trichloroethane must be more denser then xylene.
Zinc is denser, because a pellet of it will sink in water. Sodium is not as dense as water, because it floats on thre surface ], when reacting with water.
Yes if it floats. Does Marble float in water? If not then the answer is no.
water
No, the latter is denser, due to higher water content.
Fruit juice is denser as it is almost all water.
yes
salt water is denser
For example, comparing olive oil with ethanol the alcohol is less denser.
Ice floats in water but sinks in champagne because it is less dense that pure water, but denser than the alcohol in champagne.
Vinegar is denser than water because vinegar is made of different substances that are denser than water, so that means vinegar is a little denser than water.
For example, comparing olive oil with ethanol the alcohol is less denser.
yes chalk is denser then water.
Because Alcohol is not a planet.
No. They have very different densities. There are several types of alcohol, but for these purposes, we will use ethanol, the alcohol found in drinks. Density of water ≈ 1g/cm3 Density of ethanol = 0.789g/cm3 Density of mercury = 13.5 g/cm3 So water is about 20% denser than alcohol, and mercury is more than 13 times denser than water. Note that the density given from ethanol is for pure ethanol. Most alcoholic beverages are mixtures, with densities between those of water and pure ethanol.
Salt water is denser than fresh water.
