Answer:
Weakening of the springs
Explanation:
coil springs are made up of iron atoms that are arranged in a particular pattern in the spring. overheating the spring will cause the rearrangement of the atoms in the spring causing the spring to lose its tension ( weakening of the springs )
although heating a spring with and quenching the heat i.e not overheating the spring will help in the hardening of the spring and keeping the atoms intact and in its natural pattern but overheating the spring will result to the dis-integration of the atoms and the rearrangement of the pattern causing the lose of tension.
