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