Problems. Which of the following statements are good representation of the second law of Thermodynamics:

A. Energy can not be created or destroyed ; it can only be converted from one form to another.

B. Knowing the total internal energy of a system is not necessary, only the change of it is important in calculations of thermodynamic parameters.

C. State variables are those parameters that are independent of the path of the thermodynamic process, and depend only on the current state of the system.

D. Natural processes occur in a direction of dispersing the energy.

E. In all processes whether natural or otherwise, the total energy is conserved.

F. During a process whether natural or not, the total entropy of the Universe always increases.

Which of the following statements is not true according to the laws of thermodynamics? Group of answer choices Work depends upon the themodynamic process. An equilibrium state of the system can be characterized by its internal energy. For an isolated system, the internal energy is either constant or increases. The change in internal energy for a system interacting with the environment is equal to the heat minus the work. Pressure and volume describe the state of the system.

Please summarize the below article in approximately 100 words: Monumental function in British Neolithic burial practices Ian Kinnes The high-risk rate of survival for the non-megalithic series of Neolithic funerary monuments, recently re-emphasized by Piggott (1973: 34), introduces a further variable into the deductive study of burial practices. In Britain and Europe the overall distribution of monumental forms present both lacunae and a marked preponderance of cairns over earthen mounds which are in ill accord with the known or predicted...
