Thermodynamics Review Flashcards

Flashcards based on Thermodynamics lecture notes.

A real gas behaves like an ideal gas at low pressure.

True. At low pressure, real gases behave more like ideal gases.

A real gas behaves like an ideal gas at high temperatures.

True. At high temperatures, real gases behave more like ideal gases.

A real gas behaves like an ideal gas as its specific volume increases.

True. As specific volume increases, a real gas behaves more like an ideal gas.

A real gas has a continuum at low specific volume.

False. A real gas has a continuum at high specific volume.

A real gas can be considered more of a continuum at higher temperatures.

False. A real gas is in continuum at low temperature.

If a system is in thermal equilibrium, the temperature can change.

False. The temperature remains constant in thermal equilibrium.

If a system is closed, energy can flow throughout it.

True. Energy can flow throughout a closed system.

Energy can cross a boundary in a closed system

False. Energy cannot cross a boundary in a closed system

Specific volume is an intensive property.

True. Specific volume is an intensive property.

The three mechanisms of heat transfer are conduction, convection, and radiation.

True. The three mechanisms of heat transfer are conduction, convection, and radiation.

A non-rigid tank has constant volume

False. A Non-rigid tank has constant volume.

Quality (X) is m(vapor)/m(total)

True. Quality (X) is m(vapor)/m(total)

Is this course a microscopic view of thermodynamics

False. This course is not a microscopic view of thermodynamics.

A closed system always contains the same matter, there is no transfer of matter across its boundary

True. A closed system always contains the same matter.

Two systems are in thermal equilibrium if there is no heat transfer between them.

True. Two systems are in thermal equilibrium if there is no heat transfer between them.

Does heat transfer need a medium?

False. Heat transfer can occur through a vacuum.

If Bob leaves the refrigerator open in a house with good insulation, what happens to the temperature?

Increases. Leaving the refrigerator open adds heat to the room.

The work done between A and B is different.

Different. The work done depends on the path.

Zeroth Law of Thermodynamics

If two systems are each in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other.

Adiabatic process

A thermodynamic process where no heat is transferred between a system and its surroundings.

Convection

The transfer of energy between a solid surface and the adjacent fluid that is in motion, and it involves the combined effects of conduction and fluid motion.

If you are sitting next to a radiator, what type of energy is transmitted?

Radiation and Convection

Heat and work are boundary phenomenons

Boundary phenomenon. Only observed at the system's boundary.

Vig

Volume change per unit mass during a vaporization process.
