But how is enthalpy difference equal to work output in an isentropic process? Why not use internal energy instead, since isentropic processes are adiabatic and the dQ is zero?
Enthalpy in adiabatic process
Did you know?
WebA throttling process is a thermodynamic process in which the enthalpy of the gas or medium remains constant (h = const). The throttling process is one of the isenthalpic processes. During the throttling process, no work is done by or on the system (dW = 0), and usually, there is no heat transfer ( adiabatic) from or into the system (dQ = 0). WebThis physics video tutorial provides a basic introduction into adiabatic processes. An adiabatic process occurs when the transfer of heat is equal to zero. ...
WebJan 30, 2024 · Adiabatic •This is a process where no heat is being added or removed from the system. •Or can be simply stated as: no heat transfer (or heat flow) happening in a system. •In freshman chemistry, only the basic idea of this process is needed and that is when there is no heat transfer, Q = 0.
