Determine whether the statement is True or False.
For a well-insulated system, the change of total energy is equal to the work done by the system in the process.
The statement is TRUE cause for any system (open or closed) the net energy transfer is associated with either heat transfer or work transfer or both at the same time.
For an ISOLATED SYSTEM the net heat transfer is ZERO.
so the energy transfer will now cause only the work interaction of the system.
As for an open system-

And since the heat transfer with surroundings is zero.

For an closed system -

13. Indicate whether the following statements are true or false. If false, correct the statement so that it is true. a. A change in enthalpy for exothermic chemical reactions is negative. b. An endothermic reaction is one in which enthalpy is absorbed by the system from the surroundings. c. Condensation of water vapor is an example of an endothermic process. d. Heat, q, and enthalpy, AH, are state functions, meaning they depend on the path taken, and q = AH....

Indicate whether each statement is true or false. (a) The entropy of the universe increases for any spontaneous process. (b) The entropy change of the system is equal and opposite that of the surroundings for any irreversible process. (c) The entropy of the system must increase in any spontaneous process. (d) The entropy change for an isothermal process depends on both the absolute temperature and the amount of heat reversibly transferred.
Determine whether the following statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. If one or more data items are much greater than the other items, the mean, rather than the median, is more representative of the data.
