In thermodynamics, a reversible process is a process whose direction can be returned to its original position by inducing infinitesimal changes to some property of the system via its surroundings. The debate specifically says "Do you agree or disagree with euthanasia or mercy killing?".
Assuming the process is irreversible and adiabatic.
As the ammonium chloride is decomposing as fast as the ammonia and hydrogen gas is coming together there is no net change in the amount of each substance present. thermodynamics temperature pressure. Ask Question Asked 5 years, 9 months ago. The one physical phenomenon I am unable to explain with the second law is the origin of life. Reversible Changes in Shape of Red Cells in Electrical Fields.
We represent dynamic equilibrium using reversible reaction arrows: NH 4 Cl (s) ⇄ NH 3 (g) + HCl (g) The dynamic part indicates that reactions are still on going. 19 silver badges.

NCERT Solutions for Class 7, Chapter 6 (Physical & Chemical Changes) is available here. Although in some cases, involuntary euthanasia has a … The formation of complex organic molecules would go from a more likely state to a less likely state. By contrast, an example of an irreversible reaction would be cooking an egg, which causes the proteins to denature. The question does not give a value of moles. Throughout the entire reversible process, the system is in thermodynamic equilibrium with its surroundings. Having been reversed, it leaves no change in either the system or the surroundings. 49 bronze badges. What is being advocated is the right of an individual to make a decision, not to have a say or coerce an individual to make the decision to want to die. VAT will be added later in the checkout. With this article, you can also download PDF of Class 7 Science NCERT textbook in PDF format. Assuming the process is reversible and adiabatic. All of the formulae I have on this subject include moles. A reversible reaction is one that is kinetically reversible. Diabetes is characterized by hyperglycaemia due to impaired insulin secretion and aberrant glucagon secretion resulting from changes in pancreatic islet cell function and/or mass. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Efficiency of reversible engines. ... the statement is "all reversible engines have the same efficiency when operating between the same temperature reservoirs". I.e., one where you can adjust the relative concentration of products and reactants back and forth as you change conditions.
