Thyroid hormone tells all of the cells in your body how busy they should be. Too much thyroid hormone (hypERthyroidism), and your body goes into overdrive; not enough thyroid hormone (hypOthyroidism), and your body slows down.
Place the pot on the stove and turn the heat to high. Check for steam escaping from under the lid, then lift the lid carefully to see how the water is doing. Look at the water. If large bubbles are rising from the bottom of the pot to the surface, the water is boiling.
Conventionally, the water temperature at which water boils is considered to be 100 degrees Celsius or 212 degress Fahrenheit. However, these numbers are only valid at sea level. As barometric pressure changes so too does the boiling point of water. For instance, as elevation increases the boiling point lowers. On the top of Mount Everest, for example, boiling water is possible at a water temperature of 68 degrees Celsius or 154 degrees Fahrenheit. Conversely, in deep ocean vents, water can be much hotter than that without boiling.
