Determine the molar heat capacity for the thermodynamic process depicted in the figure.

Options

  1. AC = C_V
  2. BC = C_p
  3. CC > C_V
  4. DC = 0

Correct answer

D. C = 0

Step-by-step solution

The equation of the process given in the figure is p = K V^ , which can be rewritten as pV^ = K , where K is a constant. This is the standard equation for an adiabatic process of an ideal gas. In an adiabatic process, there is no heat exchange between the system and its surroundings, which means dQ = 0 . The molar heat capacity is defined as C = dQ n dT . Since dQ = 0 , the molar heat capacity for this process is C = 0 .
