Explanation:
The particles in [type here] water are more spread out and become [type here] dense. This causes the water to and stay at the [type here]. In [type here] water, the particles move [type here] together and become [type here] dense. So, the cold water [type here] and stays at the bottom.

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
