In a nuclear power station, which step of the process converts energy of other forms into electrical energy that can be used as electricity

Steam forces the high-pressure turbine to turn.

Explanation:

Hello,

Producing electricity via nuclear power stations involves energy conversion from one form to another until energy in the form of electricity is obtained. Typically, the splitting of uranium atoms through the process of nuclear fission is performed to produce heat energy that is used to boil water into high-pressure steam which turns or spins the fans in the turbines that powers the generator to obtain the electricity.

Best regards.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
