Homework Answers
Only statement 3 is correct.
we cannot be sure about statement 2 and 1 because nothing is given about a normal boiling point of X definitely the normal boiling point of x will be more than 74 degree Celsius but the actual value is not known so we cannot comment about statement 1 and 2.

"Vapor Pressure of Water" assignment:
VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
