State an exception to the claim that all substances expand when heated?
Ice gets smaller, and the melt water does too until it warms to 4 0C. But rubber is particularly importand because heating makes it smaller. This is why engine accessory belts squeal when cold, then they warm up and shrink. There are many useful characteristics of rubber that depend on this phenomenon.
Why does a can collapse when heated and put in water?
A heated can has under gone superficial (areal) expansion and when cooled suddenly by immersing in water "shrinks" in a very "haphazard" way leading to collapse. Now the forces at action are thermal- the so called thermal stresses. Now there is another example of how a can could collapse. Water is poured into a can and and heated so that copious steam formed could escape through an opening and then after sometime this opening is closed tightly and the can is "bathed" in cold water. The can collapses. The forces unleashed are different in this case!
