Which of the following is an equivalent cyclic process corresponding to the thermodynamic cyclic given in the figure?

Options

  1. AWhat is the consequence of fluoride ion concentration in drinking water exceeding 2 ppm?
  2. BWhat is the consequence of fluoride ion concentration in drinking water exceeding 2 ppm?
  3. CWhat is the consequence of fluoride ion concentration in drinking water exceeding 2 ppm?
  4. DWhat is the consequence of fluoride ion concentration in drinking water exceeding 2 ppm?

Correct answer

C. What is the consequence of fluoride ion concentration in drinking water exceeding 2 ppm?

Step-by-step solution

For process 3→13 \to 1, Volume is constant,
PV=nPT;PV = nPT; as P increases T increases.
For process 1→21 \to 2, the process is adiabatic process,
PVγ=P{V}^{\gamma} = Constant
⇒TVγ−1=⇒ T{V}^{\gamma - 1} = Constant.
For process 2→32 \to 3, pressure is constant,
V=kTV = kT.
