Why is PMM1 impossible?

A perpetual motion machine 1 violates the law by creating energy. All processes in universe comply with first and second law of thermodynamics. Therefore PPM1 does not and can never exist. e.g: An electric heater that consumes 1KW of electricity cannot produce more than 1KW heat.

What is PMM1 explain with suitable example?

ANSWER: Perpetual Motion Machine of the First kind (PMM1) Perpetual Motion Machine is the machine which violates the law of thermodynamics. A machine, which can supply mechanical work continuously without consumption of any energy, violates the first law of thermodynamics.

What is PMM1 and PMM2?

Perpetual Motion Machine (PMM) of the First Kind (PMM1) would be one to violate the 1st Law of Thermodynamics, to permanently produce useful energy (work) without any energy source, or to produce more ‘energy’ than consumed (thus generate energy from nowhere); and Perpetual Motion Machine of the Second Kind (PMM2) …

What is PMM1 how it violates First Law of Thermodynamics?

It can only get transformed from one form to another form. An imaginary device which would produce work continuously without absorbing any energy from its surroundings is called a Perpetual Motion Machine of the First kind, (PMMFK). A PMMFK is a device which violates the first law of thermodynamics.

Why is PMM 1and impossible?

Q – What is PMM-1 why it is impossible? It 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.

Are perpetual motion machines possible?

Is perpetual motion possible? According to Frey: No, but things can be engineered to approximate or mimic it. “The laws of physics indicate that perpetual motion would occur if there were no external unbalanced forces,” he says.

What is true for PMM1?

Explanation: PMM1 is the machine which violates the first law of thermodynamics that the energy can neither be created nor be destroyed. Therefore total energy of the universe is constant.

What is PPM 2 why it is impossible?

ANSWER: perpetual motion machine of second kind (PMM2) This is due to that some heat has to be rejected to sink. 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). PMM2 is impossible to produce.

Why is PMM2 impossible?

What is Carnot Theorem?

Carnot’s theorem, also known as Carnot’s rule, or the Carnot principle, can be stated as follows: No heat engine operating between two heat reservoirs can be more efficient than a reversible heat engine operating between the same two reservoirs.

Is PMM2 practically possible?
