Statement I: A quasi -static process is so called bacause it is a sudden and large change of the system.
Statement II: An adiabatic process is not quasi- static because it is a sudden and large change of the system.

Options

A. Statement I: is true, Statement II is true and Statement II is the correct explanation for Statement I.
B. Statement I: is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.
C. Statement I is true, Statement II is false.
D. Statement I is false, Statement II is true.

Answer

B

Explanation

It is true that for real gases, and for the real procedures in the laboratory, an adaibatic process is a sudden and large change of the system obtained in a small time. However, for an ideal gas, and for an ideal procedure, we assume for such a gas, an adiabatic process is considered quasi`-` static, in which the system passes through a continuous succession of equilibrium states, which we can plot on a `P-V` diagram. Such a process is also assumed to be reversible through, of course, a quasi `-` static process may or may not be reversible. Such ideal consitions as we assume may not be obtained in particle but almose all real systems deviate little from the results of our ideal procedures, which may therefore be considered approximations to real processes.
