Why bread becomes hard with age while the cookies and crackers become soft with time?
Bread, if left out for too long, will become stale. This happens for 2 reasons. One, if the bread was hot, it would be softer. As it cools, the crust will harden. Otherwise, air causes the soft-ness of the bread to deplete. The air can dry out the bread, cool it off, harden the crust, take the moisture out, and possibly cause it to grow mold (if you leave it for TOO long). Some cookies / crackers will do the same. Others will become mushy. This happens as the bonds within the cookie / cracker that made it crunchy or firm begin to loosen. As moisture seeps into a cookie / cracker, that bond will also weaken and it will become softer with time.

you should keep bread airtight because the more air that isn't circulating through that particular loaft of bread the softer the bread will stay and the fresher the bread will be.you wouldn't have crustied up bread if you keep it airtight. air is of cours, going to insert itself inside the loaft of bread when you open up the loaft to grap you a piece. After you have grabbed you a piece of bread make sure you push as much air out of the bread bag as you can and it will prevent the bread for being less fresh.
Why does bread mold faster in a zipoc bag?
Bread molds faster in a ziploc bag because the plastic bag creates a warm and moist environment that is conducive to mold growth. Additionally, sealing the bread in a ziploc bag traps moisture and prevents air circulation, creating an ideal environment for mold spores to multiply.
