Vapor pressure and heat evaporation lab report vapor pressure and heat of vaporization introduction: evaporation is the process of a liquid becoming vaporized when a liquid is placed into a confined space some of the liquids will evaporate.
1 vapor is the term for a gas produced from the vaporization of a liquid if it is assumed that the resulting vapor is an ideal gas, then we can use the ideal gas law: by substituting moles for mass and molar mass the following equation is. 1 the molar mass of a condensable vapor reading assignment: chang, chemistry, 10th edition, pp 85-87 185-187 goals to determine the molar mass of a condensable vapor through use of the ideal gas law. Definition the vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor are in dynamic equilibrium if we were to place a substance in an evacuated, closed container, some of it would vaporize.
Vapor pressure example using the ideal gas law. Chloroform is a commonly used laboratory solvent it was previously used as an anesthetic, but was banned from use in the us due to its suspected carcinogenicity. The purpose of this experiment is to determine the enthalpy of vaporization of water by taking note of the vapor pressure of water over many temperatures and applying the clausius-clapeyron equation.
Vapor pressure the macroscopic view the vapor pressure of a liquid is the equilibrium pressure of a vapor above its liquid (or solid) that is, the pressure of the vapor resulting from evaporation of a liquid (or solid) above a sample of the liquid (or solid) in a closed container.
