Given, atmospheric pressure =646 mm Hg. we are asked, what will be the effect on boiling point of water.Boiling point : It is a temperature at which atmospheric pressure is equal to vapor pressure liquid (water in this case). implies that, an increase in the atmospheric pressure will increase the boiling point of liquid and a decrease in atmospheric pressure will lower the boiling point.This happen because, the vapor pressure is the function of temperature, it increases when temperature increases and it loweredwhen temperature decreases.And normal atmospheric pressure =1 atm =760 mm Hg.and here given atmospheric pressure =646 mm Hg , which is lower than the normal atmospheric pressure.Thus, the boiling point of will be less than 100 °C.Hence , option (a) is correctTherefore, the boiling point of water will be less than 100 °C , and henceoption (a) is correct.

The atmospheric pressure in Ogden, Utah is 646 mm Hg.
