The process AB is shown in the diagram. As the gas is taken from A to B, its temperature    (A) initially increases then decreases                                                                                        (B) initially decreases then increases                                                                                        (C) remains constant                                                                                              PLEASE EXPLAIN

The correct option is (A) initially increases then decreases

Internal energy is directly proportional to temperature. So if there is an increase in temperature, there is also an increase in internal energy.

Now,

Let us first find the equation of the straight line,

∴ equation of the line :

We know that internal Energy (U) = PV

  • As we go from point A to point B volume increases.
  • As volume increases internal energy initially increases and then decreases,
  • since the internal energy as a function of the volume is a downward parabola.
  • If internal energy is initially increases and then decreases then temperature also initially increases and then decreases
