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.
Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. ... When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green.
