Solids
The particles in solids are very close together. They are tightly packed, giving solids high densities.Liquids
The particles in liquids are close together. Although they are randomly arranged, they are still tightly packed, giving liquids high densities. The density of a substance as a liquid is usually only slightly less than its density as a solid. For example, the density of solid aluminium is 2.72 g/cm3 and the density of liquid aluminium is 2.38 g/cm3. This means that liquid aluminium floats on top of solid aluminium.Water is different from most substances: it is less dense as a solid than as a liquid, because its particles move apart slightly on freezing. This is why ice cubes and icebergs float on liquid water.Gases
The particles in gases are very far apart, so gases have a very low density.
<span> A solid, steady energy level is very important for the brain. The brain uses almost one-third of our calories. Any fluctuations or low levels of energy will have enormous impacts on our nervous system and emotions as well. </span>
<span> This has been demonstrated and is well-known in the case of hypoglycemia. In this condition, the brain does not receive a steady supply of glucose. Common symptoms can mimic many emotional and physical disorders. These include fatigue, depression, anxiety, confusion and even violence and psychosis.</span>
<span> Emotionally speaking, when one is tired, decision-making and all other mental and emotional factors are more difficult. Thousands of people today suffer from low energy levels. This often results in feelings of depression, anxiety, mood swings, irritability, withdrawal and more.</span>
