Explanation:
Given that rigid tank is a closed system, the following model is constructed after the First Law of Thermodynamics:



The entropy generation inside the rigid tank is determined by appropriate application of the Second Law of Thermodynamics:



The properties of the steam are obtained from steam tables:
Intial State






Final State






The entropy change of the steam during the process is:


Answer: (A) Security regression testing
Explanation:
The security regression testing is used to prevent the re-occurring process. The regression testing is the type of the testing that intends to affirm that a program or code or application changes has not influenced existing highlights and it keeps up the agenda.
The agenda ought to be similarly identified with necessity that was concluded. By checking this both then relapse testing occurs and this won't reoccurred from next time.
The regression testing improvements groups must ensure that changes, updates and new discharges don't presents imperfections and vulnerabilities that could be misused by the people.
