Liquid Vinegar Mineral water Fresh Milk Oil Gasoline Kerosene Pounds per Gallon 8.45 8.33 8.34 7.497 5.664 6.664
The Correct Answer and Explanation is:
To answer your question regarding the liquid densities, let’s break down the data for each liquid based on its density (measured in pounds per gallon):
- Vinegar: 8.45 pounds per gallon
- Mineral water: 8.33 pounds per gallon
- Fresh milk: 8.34 pounds per gallon
- Oil: 7.497 pounds per gallon
- Gasoline: 5.664 pounds per gallon
- Kerosene: 6.664 pounds per gallon
Explanation:
Density is defined as the mass of a substance per unit volume. In this case, the given values are in pounds per gallon (lb/gal), which tells us how much each liquid weighs for a specific volume. The higher the value, the heavier the liquid.
- Vinegar (8.45 lb/gal) is the densest liquid in this list. This is because vinegar, an aqueous solution of acetic acid, has a higher concentration of solutes, which results in a greater mass per unit volume compared to pure water or other liquids.
- Mineral water and fresh milk both have similar densities, around 8.33 and 8.34 lb/gal, respectively. Fresh milk has dissolved fats and proteins, while mineral water primarily consists of water and dissolved minerals, giving them closely comparable densities.
- Oil has a significantly lower density (7.497 lb/gal) compared to water-based liquids. This lower density is due to the fact that oils generally consist of non-polar molecules, which are less dense than water molecules.
- Gasoline (5.664 lb/gal) is even less dense, which is typical for hydrocarbons. Gasoline has a much lower molecular mass compared to liquids like vinegar or milk, making it lighter per unit volume.
- Kerosene (6.664 lb/gal) is slightly denser than gasoline, as it contains longer hydrocarbon chains, making it heavier but still less dense than aqueous liquids.
In conclusion, vinegar is the densest liquid on this list, while gasoline is the lightest. The variation in densities mainly reflects the molecular composition and the types of compounds each liquid consists of.
