Answer:
Isotopes have same atomic numbers, no. of protons and no. of electrons. Only their no. of neutrons and atomic mass are changed.
<u>Na - 24:</u>
Atomic Mass = 24
Atomic No. = 11
Hence,
No. of protons in Na-24 = 11
No. of neutrons = Atomic Mass - Atomic Number
No. of neutrons = 24 - 11
No. of neutrons = 13
Atomic Number = 11

The correct answer should be that Potential energy increases, and kinetic energy increases, since they both increase as the temperature changes.
The answer is (4) solid to gas. The entropy is the measurement of disorder. The entropy of CO2 under different status will increase from solid to liquid to gas. So the answer is (4).
