In thermodynamic processes, which one of the following statements...

In thermodynamic processes, which one of the following statements is 'NOT' correct ?

Options

  1. AIn an isothermal process, temperature remains constant.
  2. BIn an adiabatic process, Pvγ=Pv^\gamma = constant.
  3. CIn an isochoric process, pressure remains constant.
  4. DIn an adiabatic process, there is no exchange of heat with the surroundings.

Correct answer

C. In an isochoric process, pressure remains constant.

Step-by-step solution

In an isothermal process, the temperature of the system remains constant (T = constant).<br><br>Inanadiabaticprocess,thereisnoheatexchangewiththesurroundings(Q=0constant).<br><br>In an adiabatic process, there is no heat exchange with the surroundings (Q = 0) and the relation PVγ=PV^\gamma = constant holds true for an ideal gas.

In an isochoric process, the volume of the system remains constant (V = constant).Theprocesswherepressureremainsconstantiscalledanisobaricprocess.<br><br>Thus,thestatement′Inanisochoricprocess,pressureremainsconstant′isincorrect.<br><br>Answer:Inanisochoricprocess,pressureremainsconstant.constant). The process where pressure remains constant is called an isobaric process.<br><br>Thus, the statement 'In an isochoric process, pressure remains constant' is incorrect.<br><br>Answer: In an isochoric process, pressure remains constant.
