Question

why bonding between atoms break at high temperatures.

Answer 1

bcoz that much energy is sufficient to over come the bond energy

Answer 2

Because you are putting energy into the molecules, therefore, the energy then causes the bonds to break apart.

Answer 3

In case of metals, when heated up with excess temperatures they convert in to liquid form.
Is this phenomena causes due to bonds break down.

Answer 4

yaaa you are right its due to breaking of metallic bonding but not completely :)

Answer 5

But when it cools down the metal again retains is solid state. That means the broken bonds are again formed. How can broken bonds can form again.
How can this phenomena is viewed.

Answer 6

thats why i said they don't break completerly

Answer 7

do you mean breaking half. Or is there some elasticity like loosing their strength and retaining original form.

Answer 8

yaaa its hard to say breaking half but some thing some interaction between those atoms have been lost :) still the what is metallic bonding is a question of debate :) they say its band some say its sea of electrons this si all makes it difficult to understand the following :)

Answer 9
