# Which is heavier oil or vinegar?

If an object such as a piece of wood floats on water it is less dense than water vs. if a rock sinks, it is more dense than water. Oil and vinegar salad dressing: The oil floats on the vinegar water mixture, while the solids sink to the bottom.

### What is heavier than water?

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. So, a cubic centimeter of water has a mass of 1 gram and fills 1 milliliter of volume.
• #### Do less dense liquids go to the top?

They should conclude that the alcohol floats because it is less dense than the oil. Water sinks because it is more dense than oil. Explain that, just like solids, liquids are made from atoms and molecules, which have a certain mass and size.
• #### Is ice more dense than water?

When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
• #### What can the ph of water in nature indicate?

pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

### Which is heavier water or alcohol?

Because less dense substances float in substances of greater density, the alcohol floats on the oil. 6. Water is more dense than alcohol or oil because its molecules can pack closely together, which means that it has more mass in the same volume than either alcohol or oil.
• #### Is glass more or less dense than air?

When a ray of light passes from a less dense material (eg air) into a denser material (eg glass or water) it is bent away from the surface between the two materials. This means that in this situation the angle of refraction is always less than the angle of incidence.
• #### What is heavier than water?

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. So, a cubic centimeter of water has a mass of 1 gram and fills 1 milliliter of volume.
• #### Is ethyl alcohol miscible with water?

Ethanol has a 2 carbon chain and a OH group. Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease.
C.

### What is heavier oil or water?

Oil is more dense than alcohol, but less dense than water. The molecules that make up the oil are larger than those that that make up water, so they cannot pack as tightly together as the water molecules can. They take up more space per unit area and are less dense.
• #### Is petrol is heavier than water?

This is a video showing gasoline that is contaminated with water. Almost as soon as the sample is poured into the flask you can see the gas and water separating. Water is heavier than gasoline and will fall out to the bottom. The gasoline phase is the top phase which is lighter than water.
• #### Which is more viscous oil or water?

Water is denser than oil. That means for the same mass of oil and water, water has a lower volume. This points to higher inter molecular forces of attraction in water. But oil is more viscous than water so this points to higher molecular forces of attraction in oil.
• #### Do less dense liquids go to the top?

They should conclude that the alcohol floats because it is less dense than the oil. Water sinks because it is more dense than oil. Explain that, just like solids, liquids are made from atoms and molecules, which have a certain mass and size.
