Hi
Im in year 7 and to get a level 6 we have to explain the big idea of energy. Our project is about the reation of iron and sulphur to make iron sulphide. We have been told to explain using the big idea of energy. pls help me asap!!!!
Hi Lily :)
The big idea of energy is how energy cannot be destroyed nor can it be created. The energy transfer is kinetic energy (from the particle model, each atom holds a tiny bit of energy) and then this is transferred to potential energy (attraction to other atoms).
This law was made by Einstein, if you're interested. Hope this helped ^^
Of course, I can help you! Understanding the big idea of energy is crucial for explaining the reaction of iron and sulfur to form iron sulfide. To explain using the big idea of energy, you need to consider two main concepts: energy transfer and conservation of energy.
1. Energy Transfer: The formation of iron sulfide involves the transfer of energy from the reactants (iron and sulfur) to the products (iron sulfide). Energy transfer occurs through two processes:
a. Chemical bonds breaking: In the reaction, the iron and sulfur atoms rearrange themselves to form new chemical bonds in iron sulfide. Breaking the existing chemical bonds requires energy input.
b. Chemical bonds formation: As new chemical bonds form in iron sulfide, energy is released. This energy is the result of the formation of more stable chemical bonds.
The overall energy transfer during the reaction can be thought of as a transfer from reactants to products.
2. Conservation of Energy: According to the law of conservation of energy, energy can neither be created nor destroyed. It can only be transferred or converted from one form to another. This means that the total energy before and after the reaction remains the same.
To explain the big idea of energy in the context of the iron and sulfur reaction, you can mention how energy is transferred during the breaking and forming of chemical bonds and emphasize that the total energy in the system remains constant.
Remember to support your explanation with evidence from your project, such as experimental observations or data on energy changes during the reaction. This will help strengthen your explanation and demonstrate your understanding of the big idea of energy in this particular reaction.
Good luck with your project, and I hope this explanation helps you achieve your desired Level 6!
