Question

1a. What is vapor pressure and why does it change with temperature?
1b. What is enthalpy of vaporization?
1.cThe assumption was made that the vapor pressure of water is negligible at a temperature close to zero. Find the actual vapor pressure at your low temperature and comment on the validity of the assumption.
1.D The assumption was also made that the slight changes in "h", the depth under the surface of the water, will not significantly change the total pressure in the graduated cylinder. Comment on the validity of this assumption
