- The system is expanded from equilibrium state a to equilibrium state b in the process of I, absorbing 500J of heat, working externally 400J; Then it is compressed to the original state a in the process of II, releasing heat 300J outward. Then, in the process of II, the change of the internal energy is[img=178x135]17e0b762b3b1660.png[/img] A: -100J B: 100J C: 200J D: -200J
- In the “Articles of Confederation”, each state kept its sovereign dependence and control over all of its internal affairs.
- When did India gain its independence and become a __________state?
- The 3s state of Na has an energy of -5.14 eV. Its effective nuclear charge is ( )
- Each time a pulse is applied to the clock input of a flip-flop, its outputs change their logic state from high (logic 1) to low (logic 0) or vice versa.
