Fill in the blanks:

To make electricity:

Coal heats water ---> heat makes _______ ---> turbines turn

I hope this version makes more sense that the previous one. :P

steam

To complete the sentence, "heat makes _______," we need to understand the process of generating electricity. Here's how it works:

1. Coal is burned to produce heat.
2. The heat is used to boil water, creating steam.
3. The steam is directed towards turbines.
4. As the high-pressure steam flows through the turbines, it causes them to spin.
5. The spinning turbines are connected to generators, which convert the mechanical energy of the turbines into electrical energy.

So, to fill in the blank, the correct answer is "steam." The heat generated by burning coal converts water into steam, which is then used to turn turbines and generate electricity.
