Temperature changes related to elasticity

Question

A weight is suspended from a long metal wire. If the wire suddenly breaks,its temp will? Ans- rise

1)How??

2)Does it matter if it 'suddenly ' breaks or not?Would the answer change if not?

Answer 1

Heat decreases the hardness of the material.  In other words, the material becomes weaker as you increase temperatures, making it easier to break.

 

Look up the heat treatment process "Annealing".

 

 

It does matter if a material breaks or not.  If it suddenly breaks, then you would not want to use that material for any long-term use.
