The answer is A because the subject is responding to something that is going on outside of it, if that makes any sense :)
Hope this helps! Have a great day!
Answer: The given statement is true.
Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.
General equation of ionization energy is given by:

- If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.
- And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.
Hence, the given statement is true.
A watt IS by definition a J/s so and so an 18000 W station will use 18000 J/s so it is C
Answer:The real answer is D
