6A. State whether each of the following is true or false. Explain your reasoning in each case. (a) q must be zero for an isothermal process (b) q=0 for every cyclic process [A cyclic process is one that begins in one state and undergoes several steps which ultimately bring the system back to the same initial state.] (c) DU=0 for every cyclic process. (d) DT=0 for every adiabatic process in a closed system.

Step 1
(a) According to the first law of thermodynamics, the internal energy change of the system is given by:
Here delta E = change in internal energy
q = heat transfer of the process
w = work done during the process
The internal energy of the system is a function of the temperature. For the isothermal process:
Thus the given statement is false.
