Finally, despite the high energy density of Li-ion compared to other kinds of batteries, they are still around a hundred times less energy dense than gasoline (which contains 12,700 Wh/kg by mass or 8760 Wh/L by volume). When these tanks have the right balance of air and water, the submarine's average density equals that of the surrounding water, so it will neither float nor sink. The next dense will float on top of that, and the least dense will float at the very top. Which was more dense, the salt water or the sugar water? A ship is built to float because its average density is less than the density of water. Density is the mass (grams or pounds or whatever else) of an object divided by its volume (liters or gallons or whatever else). Text density or Lexical density is defined by the ration of the total number of lexical words (or content words) by the total number of words used in the document. Particle density and bulk density are two basic ways to express sediment weight. Since water is much denser than air, this increases the average density of the submarine. Best For:
