Question

The first law of thermodynamics says that heat added to a system always results in work being done.        True.        False. . 2. In a reversible isothermal process, there is no change in internal energy.        True.        False. 3. An adiabatic process is one that involves no work.        True.        False. 4. If a gas undergoes an isobaric expansion, it means that the temperature does not change.        True.        False.  5. The second law of thermodynamics applies to a closed system.        True.        False.  6. A heat pump (like a refrigerator) operating between two different temperatures requires work input.        True.        False. 7. When a body is cooled, its entropy increases.        True.        False.  8. If two objects are at different temperatures initially and then are allowed to come into equilibrium, the entropy of the system remains constant.        True.        False.
