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.
4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion of water when you cool it to lower temperatures is unusual, since most liquids contract when they're cooled.
