A little precision to Q.2: The water boils at 100 degrees Celcius (but only at sea level!). The boiling point of water decreases with elevation comparing to sea level. Most parts in Florida are nearly at sea level. But, for example, at Denver, Colorado (the city is located 5,414 ft above sea level) the boiling point of water is around 94.6 degrees Celcius (202 degrees Fahrenheit).
