Irréversible (French pronunciation: [iʁevɛʁsibl]) is a 2002 French psychological thriller drama film, written and directed by Gaspar Noé and starring Monica Bellucci, Vincent Cassel, and Albert Dupontel. The film employs a reverse chronology and follows two men through the streets of Paris as they seek to avenge a brutally raped girlfriend. Much of the film's soundtrack was composed by Thomas Bangalter, one half of the former electronic music duo Daft Punk.
Irréversible competed for the Palme d'Or at the 2002 Cannes Film Festival and won the Bronze Horse at the Stockholm International Film Festival.
Irréversible has been associated with a series of films defined as the cinéma du corps ("cinema of the body"), which according to Palmer includes: an attenuated use of narrative, assaulting and often illegible cinematography, confrontational subject material, and a pervasive sense of social nihilism or despair. Irréversible has also been associated with the New French Extremity movement.
The film was particularly controversial upon its release for its graphic portrayal of violence, specifically the scene where a man is savagely bludgeoned to death with a fire extinguisher and its 10-minute long take rape of Alex (Monica Bellucci), who is then brutally beaten into a coma. The film also attracted accusations of homophobia. American film critic Roger Ebert called Irréversible "a movie so violent and cruel that most people will find it unwatchable".
What is the concept behind 'irreversible adiabatic process' ? Why is the expression for work done in this case different from that when it is reversible?
I need some clarification on the following points on the reversible and irreversible reactions.
In the examples cited in textbooks, for reversible reaction, isothermal expansion and compression are given. But the adiabatic exp and comp are not given.
Why is it not included in the list...
Hopefully somebody can help me with this. I have a final exam next week, and the textbook we use along with my professor didn't do a good job explaining what happens in irreversible reactions.
More specifically, what differences are there between reversible and irreversible processes of...
I know work for reversible + isothermal is w=nRTln(v2/v1) but what about irrev? I see the equation W=P(delta V) used all the time. Is this the correct one to use? or is there another equn for irreversible work for a gas?
THanks
My textbook tries to prove that for Entropy of Irreversible Process > 0 by using the example of irrev expasion into a vacuum which doesn't make sense to me.
If work is = 0 then no heat is exchanged between the sys and surrounding so qsurr = 0
s(uni) = s(sys) + 0
since S(sys)=qirr/t and no...
Our laws that describe entropy to be irreversible using our macroscopic experiments in which they always come out with a certain outcome. However, I think there is no such thing as an irreversible process on a quantum level and the quantum level is the stronghold of everything. Everything is...

In trying to understand the underlying mechanics of irreversible processes, I came up with four mechanical asymmetries that seemed relevant to describe energy transfer through the bulk motion of a frictionless piston that divides a cylinder with two gasses of same pressure but different...

Hi everybody.
I give you an example to clarify my question:
a NAND gate is irreversible becuase you can not find inputs from outputs and this is because of one bit is lost in output ( Antropy will increase ).the number of inputs and output are not the same in NAND gate.
ok...now my question...
I am confused about the entropy change for reversible and irreversible cycles. I know entropy is a state function, so for cycles, the entropy change within the system should be 0, since the process ends up in the same state as the beginning. So does this mean that the entropy change for the...
Suppose that one mole of a monatomic perfect gas at 27°C and 1.00 atm pressure
is expanded adiabatically (i.e. no heat transfer, so that the temperature must fall) in two
different ways: (a) reversibly, to a final pressure of 0.5 atm, and (b) against a constant
external pressure of 0.5 atm...
Hello Lords of Physics,
sorry for pestering you guys again but these days a question about irreversibility is pestering me , my question is
Why we say that irreversibility in process is due to finite tempreture difference ?
so if there is finite temp diff. why process is not reversible...
work done in an reversible process is easy to find we have the function of P internal bt when it comes to irreversible process then how do we find work done by the gas or on it and if ur answer is (sry i am new to forum i don't know how to use the features) [ integration p external dv] then...

A balloon featured with a negligible thermal capacity contains V_{l}=3l of ideal gas and is immersed in a lake (thermal bath) at the depth of h_{l}=10m beneath the lake surface. If it is brought to the depth of h_{l}=3m, how much is the heat exchange?
Hi,
I was wondering something. Exactly what is meant by a thermodynamically reversible/irreversible process? What are their relation to spontaneous processes? These concepts seem to be fundamental to the understanding of the second law, but textbooks (including the industry standard Atkins...
It is stated that the change in entropy of an isolated system during an irreversible process is > 0; while for a reversible process, it is = 0.
