Fresh water boils faster than salt water. This is because salt increases the boiling temperature and lowers the freezing temperature of water. Both fresh water and salt water will reach 100 degrees Celsius (212 Fahrenheit) at roughly the same rate, but salt water will only boil at a higher temperature (depending on the concentration of salt). Another factor that affects the boiling and freezing points of water is altitude. The higher you are - the lower the boiling point and the higher the freezing point.
