Question 3 (4 points) The vapor pressure of a liquid is dependent on: the temperature of the liquid and intermolecular forces of attraction in the liquid the temperature of the liquid and the surface area of the liquid only on the surface area of the liquid only the temperature of the liquid O only the forces of intermolecular attraction in the liquid Question 4 (4 points) If the atmospheric pressure over a sample of liquid is increased, the boiling point...
"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...
