It takes about 15 minutes to heat a quantity of water to 100°C.  It takes only 8 minutes to heat an equal amount of dry soil to the same temperature.  Which substance (water or soil) has the lowest specific heat capacity?  

The Inverse Square Law states that

The most common measurement system used around the world is the
