Heat released/ gained

Postby Bryce Ramirez 1J » Sat Mar 14, 2020 11:23 pm

When bonds are being broken/ formed in relation to melting points and freezing points, is energy released when a bond is broken? Or is energy gained? Similarly, is energy released/gained when a bond is formed?

When a bond is broken, energy is required because it takes energy to break bonds. Similarly, energy is released when bonds are formed.

In relation to melting / freezing points, energy will be required to break bonds (think heating up an ice cube to make it into water). The energy released when bonds are formed is less obvious, but the climate on a humid day is probably a clue.

In order for a bond to break there must have a source of energy to break that bond, and so with the formation of bonds because is typically an exothermic reaction, heat is released

It takes energy to break bonds and energy is released to form bonds

Bonded atoms are stable so it requires energy to break these bonds and move them into a less stable state. Atoms forming bonds go into a more stable state, therefore releasing energy.

Breaking a bond requires energy, so this reaction is endothermic. Forming a bond releases energy, so it is exothermic.

When a bond breaks, it requires energy to do so. Forming a bond will release energy

Energy is gained when a bond is broken and released when a bond is formed.

Think about it as when you break a bond, you need energy to break it. When you form a bond, the atoms are now more stable, releasing the extra energy.

When bonds are broken, energy is required to break the bond. However, energy is released when bonds are formed.

Breaking a bond requires energy. Forming a bond releases energy. This is due to the fact that bonds form to allow atoms to be in the lowest energy (stable) position. Breaking a bond would cause two previously bound atoms to now be separate, and this may be an unstable position for the atoms. So, breaking bonds can sometime be unfavorable and require energy. On the other hand, forming bonds might allow two separated atoms to be in a lower energy state, and this is exothermic.

Energy is always needed to break bonds and released when forming bonds

When bonds are broken, energy is gained. This is related to the boiling/melting point of a compound. When bonds are formed, energy is released. This is related to freezing/condensing.

When bonds are broken energy is required, and then they are made energy is released.

To reiterate, breaking a bond requires energy and forming a bond releases energy. Hope that helps!

It helps me to think of the molecules as they exist in a. stable state. For example, if you are disrupting this state to break bonds, then energy is required. However, if more bonds need to form to maintain stability within the molecule, no energy is needed, but rather it is released in the process.
