What does change in bond energy mean? I get that when a solid turns into a liquid that there is a change in bond energy, but what exactly does that mean? If the bond of a solid breaks and turns into a liquid will it have a change in bond energy? if the bond energy changes will it decrease or increse?

Expert Solution

In the chemical bonds of a molecule the attractive electrical forces cause bound states to exist. That is, the atoms of the molecule cannot escape the molecule without a supply of external energy. So energy needed to break this bond is known as bond energy.

As the temperature changes, bonds either get weaken or gets strong.. Thus bond energy changes.

as bond energy changes state of matter is also changes into solid, liquid or gaseous.

In solid state, bond is strong and in liquid state bond is not so strong. So bond energy decreases.

What does readiness to change mean, and what does it look like? When I worked in a large consulting firm, we had a specific step in our change process that was entitled "change readiness". But this step was akin to the "communicate" and "act" stages in the EP model. In reality, an organization that is "change ready" has incorporated the change mindset, skills and tools into its culture so that changes become part of how the company moves forward. In...
