Electrical engineers are the scientists that study the production of electricity more efficient.
<h3>
Which type of scientist would study how electricity could be produced more efficiently?</h3>
Electrical engineers are the type of scientist that would most likely study how electricity could be produced more efficiently because they produced new technologies which are cost efficient as well as produce high amount of electricity.
So we can conclude that electrical engineers are the scientists that study the production of electricity more efficient.

Neither of them are used in magnets they don’t attract metal
All sodium compounds show the same coloured flame because sodium’s familiar bright orange-yellow flame colour results from promoted electrons falling back from the 3p1 level to their normal 3s1 level. The exact sizes of the possible jumps in energy terms vary from one metal to another.
The correct answer is D:
it involves breaking molecular bonds between copper compounds
.
The explanation :
-when we melt a copper it is a physical change because the substance is still copper and have the same shape.
- but for example Burning a copper it is a chemical change. Fire activates a chemical reaction between copper and oxygen.
-The oxygen in the air reacts with the copper and the chemical bonds are broken.
- the chemical change is changing the other compound bonded to the copper atoms.
So, the correct answer is D
