Answer #1

ans:

  • Non-pv work can't be obtained from a process for which

​​Explaination:

  • Gibbe's energy is defined as "The amount of energy available from the system at given set of condition that can be put in to useful work."
  • 'in simple term Gibbe's energy is one such thermodynamic function which help in the devlopment of criterion of spontanity of process.
  • the physical significance of Gibbe's energy can be understood from the relationship between the non-pv work and Gibbe's energy change.

acoording to 1st law of Thermodynamics,relationship between G and non-pV work,

T,P = Wnon-exp.

  • so,we can say that decrease in Gibbe's energy = non-expantion work(non-pv work)done by system.
  • when is nagative process is spontanious and non pv work is said to be done while =0 system is in eqilibrium state where non-pv work cant be obtained.

If 0≤f(x)≤g(x) for x in the interval [a, b],can the surface obtained by rotating the graph of y=g(x) around the x-axis over the interval have less surface area than the surface obtained by rotating the graph of y=f(x) around the x-axis over the same interval? I have heard yes and also no so I would like some clarification. Thanks
