The CHEM TEAM site is a good tutorial site for AP Chemistry students. It is broken down in topics which relate to our text, which helps.
If you ever need to find the exact boiling point of water at different elevations and pressures, you can use the following website. When using this site, make sure that you have everything in its proper units. It wants the pressure in inches, though it might say mmHg and it gives the boiling point in Fahrenheit. http://www.virtualweberbullet.com/boilingpoint.html
Don't bother looking for a table that has freezing point changes. The change in freezing point due to elevation (pressure) is very slight; so use the value of 0 degrees C.
If you ever need to know the weather conditions, you can look them up at www.weather.com
