Answer

A) Mercury and sulfur are the two substances in the table that are in liquid state at 125 C B) In order to determine which substances are in liquid state from part A, we look both at the melting and boiling point of each substance. A substance is in its liquid state at temperatures above the melting point and below the boiling point. In part A, consider the temperature at 115 C, which is between the melting point and boiling point of mercury, which says that mercury is a liquid at this temperature C) The substances in the table may also be listed in order of increasing boiling point. Ordering by color or states would not be good ways to list because several substances share these properties.
