What condition exists in an adiabatic throttling process a. enthalpy is variable b. enthalpy is constant c. entropy is constant d. specific volume is constant
Jawaban
Penjelasan
### An adiabatic process is one where no heat is transferred to or from the system. A throttling process is a type of adiabatic process where the system's pressure and temperature change, but the volume remains constant.
## Step2: Identifying the properties of an adiabatic throttling process
### In an adiabatic throttling process, the system's enthalpy (H) remains constant. This is because the throttling process is a type of isentropic process, where the enthalpy is conserved.
## Step3: Evaluating the options
### Given the properties of an adiabatic throttling process, we can evaluate the options. The enthalpy is constant in an adiabatic throttling process, not variable. The entropy is not constant in an adiabatic process, it changes. The specific volume is not constant in a throttling process, it changes with the pressure and temperature.
