Several liquids have a lower density than water. Here are a few examples:
Oil: Most oils, such as vegetable oil, olive oil, and sunflower oil, have a lower density than water. This is why oil floats on top of water.
Alcohol: Some types of alcohol, like ethanol (commonly found in alcoholic beverages), have a lower density than water.
Gasoline: Gasoline has a lower density than water, which is why it floats on the surface of water.
Acetone: Acetone, commonly used as a solvent, has a lower density than water.
It's important to note that density is a property that depends on temperature and pressure. The density values mentioned here are approximate and can vary depending on the specific conditions.
