Which of the following are true about a simple compressible

Which of the following are true about a \"simple compressible system\"? (select all that applies)

1. It may not have any heat transfer to or from the system.

2. It can be composed of any phases of a substance: solid, liquid, and/or gas

3.It cannot be a mixture of different substances (e.g. oxygen and nitrogent)

4.Magnetization is a relevant reversible work mode

5.It\'s state is specified if given two independent, intensive thermodynamic properties

6.It\'s only relevant reversible work mode is associated with expansion or compression

Solution

1. True. It may not have any heat transfer to or from the system.

3. True. It cannot be a mixture of different substances

5. True. We need n+1=2 additional independent intensive variables to define a state.

6.True.It\'s only relevant reversible work mode is associated with expansion or compression. Mainly only reversible work mode is fluid compression.

2. False. It cannot be composed of multiple phases.

4. False. The only relevant reversible work mode in simple compressible system is by fluid compression.
