In this worksheet, we will practice describing the properties of ideal gases in which particles have zero volume and collide elastically.
Q1:
Which of the following statements is incorrect?
- AThe entropy of a system always increases with an increase in temperature under either constant-volume or constant-pressure conditions.
- BIn cyclic thermodynamic processes, it is always true that the net changes in internal energy (), entropy (), and enthalpy () of a system are zero (i.e., ).
- CIn reversible adiabatic processes, it is always true that and (work).
- DAn isothermal expansion of an ideal gas always gives and .
