In a cyclic process something has to be moved in what we call a cycle, and movement needs energy to be provided in some way. For example the "rain water cycle" has the Sun as a heat source, causing evaporation to move water from the ground to the air. It then rises to form clouds, which, when big enough, cannot hold the water drops, so causing rain (or it may be fog or snow) which thus returns the water to the earth again.
Similarly the 4 stroke cycle of a car or motor bike engine would not be able to move the machine unless there was fuel to be burned inside the cylinders.

Why does work done is zero in isochoric process?
In an isochoric process, the volume remains constant. Since work is defined as the force applied over a distance, and no mechanical work is performed when there is no change in volume, the work done in an isochoric process is zero.
Is the work-done in isothermal system is zero why?
In an isothermal process, the temperature of the system remains constant. Since work done is the result of a change in energy, and the temperature does not change, there is no transfer of energy in the form of work during an isothermal process. Thus, the work done in an isothermal system is zero.
When is workdone by force is zero?
Work done by a force is zero when the force is applied perpendicular to the direction of motion of the object. Another scenario is when the force is applied but there is no displacement of the object.
Is it possible workdone is zero although body is moving?
Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.
Work done in a free expansion process is?
In a free expansion process, no work is done because there is no external pressure or constraint on the system. The gas expands into a vacuum freely without any opposing force to overcome, resulting in no work being performed.
Work done is Zero for which process?
In throttling process, work done is zero.
Why does work done is zero in isochoric process?
In an isochoric process, the volume remains constant. Since work is defined as the force applied over a distance, and no mechanical work is performed when there is no change in volume, the work done in an isochoric process is zero.
How cyclic integral of a point function is zero?
the cyclic integral of this is zero
What is the maximum amount of work that a gas can do during a constant-volume process?
The maximum amount of work that a gas can do during a constant-volume process is zero, because work done by a gas is given by the formula W = PΔV and volume change (ΔV) is zero in a constant-volume process.
What is work done if there is nodisplacement is 0?
Work Done = Force x Displacement, so if the displacement is zero, the work done will be zero. There will be no work done.
Is the work-done in isothermal system is zero why?
In an isothermal process, the temperature of the system remains constant. Since work done is the result of a change in energy, and the temperature does not change, there is no transfer of energy in the form of work during an isothermal process. Thus, the work done in an isothermal system is zero.
What is PMM 1 why it is impossible?
WHAT IS PMM-1 A PMM1 is a Thermodynamic system that undergoes a cyclic process that produce no external affects other than the rise ( or fall) of a weight in a gravity field. WHY IS IT IMPOSSIBLE? PMM-1 state that work can still be produce in a cyclic process. This definition is against first law of thermodynamics and conservation of energy. According to first law of thermodynamics, in cyclic process E2- E1 = mg (h2 - h1) h2= h1 in cyclic process so the above equation yields E2=E1. where as according to PMM-1 you can produce work even when energy is zero (0), which makes it impossible
What is meant by zero work?
That means that no work is done.
When you ignite a matchstick then work will be done or not?
no work will be done because force is applied but displacement is zero so no work will be done.
When an object moves circular path what is the work done specify reason?
Zero work done
When is work done is zero?
Work done is zero when force acts right angle to the direction of the motion of the body . my situation of zero work done , one day i hold many books approximately 15 after some time i feel very tired but there is a physical work done is zero because i worked against right angle . i feel actual work is done because when i holding book my muscles and blood circulate all over the body so i feel work is done.

What is the difference between negative work and zero work and positive work done?
If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
