Thermodynamics Quiz

What characterizes the state of a thermodynamic system?

• Energy and work

• Mass and velocity

• Pressure, Volume, Temperature, Entropy

• Temperature and density

In a thermodynamic process, what does a positive value of Q represent?

• No heat flow

• Heat flow into the system

• Heat flow out of the system

• Work done on the system

What happens during an isochoric process?

• Heat is not transferred

• Temperature remains constant

• Pressure remains constant

• Volume remains constant

What is the relationship between internal energy and heat in a system doing no work?

• ∆U = Q + W

• ∆U = W

• ∆U = -Q

• ∆U = Q

What does the First Law of Thermodynamics state?

• Internal energy is always zero.

• Work is independent of heat.

• Heat is always conserved.

• Energy cannot be created or destroyed.

In an adiabatic process, what is true about heat transfer?

• Heat transfer is constant.

• No heat transfer occurs.

• Heat is removed from the system.

• Heat is added to the system.

What is the molar heat capacity at constant pressure (Cp) compared to constant volume (CV)?

• Cp is greater than CV.

• Cp is less than CV.

• Cp is independent of CV.

• Cp is equal to CV.

What does the work done during a thermodynamic process depend on?

• Only the initial state

• The path taken between states

• Only the final state

• The temperature of the system

What is the change in internal energy during a cyclic process?

• Positive

• Negative

• Zero

• Depends on the path

Give example for a point function

• work

• hear

• internal energy

• none of the above
