:increasing raises the boiling point of a liquid. a. the amount of liquid b. pressure c. volume

b. pressure

Explanation:

The boiling point of a substance increases as the pressure increases. The boiling points of a liquid is the temperature at which the liquid converts to vapor. At this point the vapor pressure of the liquid is equal to the pressure surrounding the liquid.

Heating increases the temperature of liquid, thereby increasing the pressure . As pressure increases the energy required to boil also increases, causing an increase in the boiling points.  

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
