    What effect does the temperature decrease have on pressure altitude?
    None. MSL altitude and altimeter setting are the only two variables in the equation,

    What effect does the temperature decrease have on density altitude?
    Higher temperature means higher density altitude. Lower temperature means lower density altitude.

    Better hit those books again!

    Galandi, a good place to go for an answer is AC 00-6B Aviation Weather, Section 4 of Chapter 5, Altimetry.
