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.
So, as the fast molecules escape, the temperature of remaining water drops. That's why evaporation cools. See Figure 2, top drawing. Water boils when evaporation occurs throughout the pot â not just on the surface â and forms bubbles that are buoyed to the top where they escape.
