A china cup breaks when the ionic or covalent bonds are broken due to shock, stress, or some other influence. Even if such a cup were broken into two simple pieces, just putting the pieces back together will not make the bonds re-form. Why? We need things like glue because of this phenomenon.
As weather balloons rise from the earths surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperatura is much lower in the upper atmosphere than at sea level. Would this temperatura effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you?
