But when the tragic incident occurs between those who are near or dear to one another--if, for example, a brother kills, or intends to kill, a brother, a son his father, a mother her son, a son his mother, or any other deed of the kind is done---these are the situations to be looked for by the poet.
When water is heated it expands. For example, water heated from 90Â°F to a thermostat setting of 140Â°F in a 40 gallon hot water heater will expand by almost one-half gallon.
The volume of water changes when the water changes state from a liquid to a solid because of the formation of hydrogen bonds within it. The bonds, which are weak, are always p â¦ resent to some degree in the liquid, but as water goes solid, the formation of hydrogen bonds sets up a molecular arrangement in the water. The bonds force the water molecules into a solid structure and they push the molecules apart to do that. The extra space the water molecules then take up makes the ice less dense than the water from which it formed. That is why ice is less dense than water, and why it floats on water as we see it does. Why does the volume of water change when it freezes? That is because the gas particle's are traped in the ice
