introduction to thermodynamics

What is thermodynamics?

• The study of energy

• The study of matter

• The study of motion

• The study of electricity

What is the conservation of energy principle?

• Energy can be created and destroyed

• Energy can change forms but the total amount remains constant

• Energy can only change forms

• Energy cannot change forms

What is the first law of thermodynamics?

• Energy can be created and destroyed

• Energy can change forms but the total amount remains constant

• Energy can only change forms

• Energy cannot change forms

What is the second law of thermodynamics?

• Energy can be created and destroyed

• Energy can change forms but the total amount remains constant

• Energy has quality as well as quantity

• Energy cannot change forms

What is classical thermodynamics?

• The study of individual particles

• The study of macroscopic behavior

• The study of statistical behavior

• The study of energy transfer

What is statistical thermodynamics?

• The study of individual particles

• The study of macroscopic behavior

• The study of statistical behavior

• The study of energy transfer

What is the zeroth law of thermodynamics?

• If two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other

• Energy can be created and destroyed

• Energy can change forms but the total amount remains constant

• Energy has quality as well as quantity

What is the state postulate?

• The state of a system is completely specified by two independent, intensive properties

• The state of a system is completely specified by its temperature

• The state of a system is completely specified by its pressure

• The state of a system is completely specified by its volume

What is an isothermal process?

• A process during which the temperature remains constant

• A process during which the pressure remains constant

• A process during which the volume remains constant

• A process during which the energy remains constant

What is a steady-flow process?

• A process during which the temperature remains constant

• A process during which the pressure remains constant

• A process during which the volume remains constant

• A process during which a fluid flows through a control volume steadily
