When a stretched wire is snapped it undergoes a change in temperature. Why?

The rate of a reaction quadruples when the temperature changes from 293K to 313K. Calculate the energy of activation of the reaction assuming that it does not change with temperature.

Let us stretch a rubber band. Is there a change in its shape?

Is the entropy change of a system influenced by the change in temperature? Explain.

A wire is stretched under a force. If the wire suddenly snaps the temperature of the wire

If a conducing wire is stretched to make itself twice longer then what change in the resistance of the wire will be seen if its resistivity and volume remain unchanged ?

A wire of uniform cross section has a resistance of 9 Omega . It is cut into three equal pieces. Each piece is stretched uniformly to three times its length and all the three stretched pieces are connected in parallel.Assuming that stretching of wire does not cause any change in density of their material ,calculate the total resistance of the combination described.

Keeping the temperature and diameter constant the length of a wire is made thrice. What change in the resistance of the wire will be seen ?
