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.
For example, water boils at 72 degrees Celsius on Mount Everest. See the Related Questions links to see how atmospheric pressure and elevation affect the boiling point of water. The boiling point of water is 100Â°C, 212Â°F or 373.15 Kelvin under standard conditions at sea level (at one atmosphere of pressure). The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation.
