10 Questions
In a steady-state, steady-flow process, mass is neither __ nor __.
Created, destroyed
For a system with multiple inlets and multiple outlets, the conservation of mass can be written on a rate basis. In this case, the mass flow rate terms are equal to __ due to no mass flow in or out of the system.
0
Closed systems are considered special forms of open systems because:
No mass flows in or out of the system
What is the resulting equation for the first law on a rate basis for steady-state, steady-flow processes?
Energy balance equation
Which type of systems assume no mass flows in or out and have a constant mass with respect to time?
Closed systems
What is the name given to the principle stating that energy cannot be created or destroyed, only transformed?
First Law of Thermodynamics
Which term can be pulled out of the derivative on the right-hand side of the energy balance equation for a closed system?
Mass of the system
'Principles of Engineering Thermodynamics' discusses the first law of thermodynamics focusing on:
Energy preservation in closed systems
'Closed systems can be considered special forms of open systems because _____.' The blank should be filled with:
'no mass flows in or out of the system'
What type of process does the conservation of mass apply to?
Steady-state, steady-flow processes
This quiz covers the concept of the Zeroth Law of Thermodynamics, which states that if two systems are in thermal equilibrium with a third system, they are also in thermal equilibrium with each other. Learn about the basis of temperature measurement and the historical background of the zeroth law.
