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
