Mechanical Properties of Fluids
In a thermodynamic process which of the following statements is not true?
In an adiabatic process, the system is insulated from the surroundings
In an isochoric process pressure remains constant
In an isothermal process, the temperature remains constant
In an adiabatic process pVγ = constant
B.
In an isochoric process pressure remains constant
For an adiabatic process, there should not be any exchange of heat between the system and its surroundings. All walls of the container must be perfectly insulated. In adiabatic changes, gases obey Poisson's law, ie pVγ = constant. In an isochoric process volume remains constant and for isobaric process pressure remains constant.
