Q. In thermodynamic processes which of the following statements is not true?
A) In an isochoric process pressure remains constant
B) In an isothermal process the temperature remains constant
C) In an adiabatic process PV^γ = constant
D) In an adiabatic process the system is insulated from the surroundings
Explanation
[Solution from source] In an isochoric process the volume is held constant; constant pressure describes an isobaric process. The other statements (constant temperature in isothermal, PV^γ = constant and thermal insulation in adiabatic) are all correct. Answer (1).
