What is the meaning of PMM2?

perpetual motion machine of the second kind
A perpetual motion machine of the second kind, or PMM2 is one which converts all the heat input into work while working in a cycle.

What is PMM1 converse?

The converse of the above statement is also true, i.e., there can be no machine which would continuously consume work without some other form of energy appearing simultaneously.

What is PMM2 in mechanical engineering?

When a heat engine produces net work output by exchanging heat with only one reservoir, then it will be represented as, Therefore this heat engine violates the Kelvin-Planck statement of second law of thermodynamics. Hence it will be a perpetual motion machine of second kind (PMM2).

What is PPM2?

Why is PMM1 impossible?

The first law of thermodynamics implies that a prepetual motion machine of the first kind (PMM-I) is impossible, because if a net amount of heat is not supplied by the surroundings during a cycle, no net amount of work can be delivered by the system.

What is PMM 2nd kind?

Perpetual motion machine of the second kind is a machine which produces work from a single heat source. In this kind of perpetual motion machine, there is only one heat reservoir, and it is being spontaneously cooled generating work without heat transfer to a cooler reservoir.

What is a PMM1 and why it is impossible?

perpetual motion machine-1 is a machine which does not obey first law of thermodynamics. we all know that ,as one cannot do the work continuously without consuming some amount of energy. perpetual motion machine works by supplying work continuously without consuming or taking in some energy. so it is impossible.

What is PPM first kind?

Perpetual motion machine of the first kind is a machine that can do work indefinitely without an energy input. From ancient, people has been captivated by this concept. The examples include the “closed-cycle water mill” proposed by the English physician Robert Fludd in 1618.
