On which condition work done in a cyclic process becomes zero?

On which condition work done in a cyclic process becomes zero?

Solution. The change in energy in a cyclic process is zero, since the initial and final states are the same. The work done and the quantity of heat gained in such a process are therefore the same with opposite signs (R = –Q).

What is the work done by 0.2 mole of a gas?

W=0. 2×2×300=120 cal.

Which of the following is not a thermodynamic coordinate?

Each thermodynamic process is distinguised from other process in energetic character according to which parameters as temperature , pressure or volume. While R is a gas constant which is not a thermodynamical coordinate.

What does the area under PV diagram indicate in thermodynamic process?

As described on the work slide, the area under a process curve on a p-V diagram is equal to the work performed by a gas during the process. An isentropic process appears as a vertical line on a T-s diagram. The area under a process curve on a T-s diagram is related to the amount of heat transferred to the gas.

Which of the following is correct for any thermodynamic system?

Hence option D is correct.

Which of the following statement is correct only internal energy?

Answer: Internal energy is a state function but notify work. ReAsOn : The change in internal energy during a process depends only upon the initial state and final state while work depends upon the path followed.

Which of the following statement is correct for Isochoric process?

Correct option a In an isochoric process pressure remains constant. Explanation:In isochoric process it is volume that is kept constant. If pressure is kept constant it is an isobaric process.

Which one is the correct option for the two different thermodynamic processes?

Correct option is (2) (c) and (d) Option (a) is wrong ; since in adiabatic process V ≠ constant.

Does reversible mean adiabatic?

Reversible adiabatic process is also called an Isentropic Process. It is an idealized thermodynamic process that is adiabatic and in which the work transfers of the system are frictionless; there is no transfer of heat or of matter and the process is reversible.

Which does more work adiabatic or isothermal?

Both start from the same point A, but the isothermal process does more work than the adiabatic because heat transfer into the gas takes place to keep its temperature constant. This keeps the pressure higher all along the isothermal path than along the adiabatic path, producing more work.
