Answer: Option (a) is the correct answer.

Explanation:

According to thermodynamics, a closed system is defined as the system in which there will be no exchange of matter takes place but there will be exchange of energy between the system and surrounding.

On the other hand, an open system is defined as the system in which there will be exchange of both matter and energy takes place between system and surrounding.

Hence, we can conclude that out of the given options accurate descriptions of closed and open thermodynamic processes is that open processes are 'flow through' processes.

Which of the following correctly describes the difference (on average) between an electron in a 2s orbital and an electron in a
bulgar [2K]

Answer:

C: electrons is the 3s orbital are higher than those in the 2s orbital

Explanation:

Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.

Also from basics we know that the energy of an orbital increases as the quantum number increases.
