Among the following, the extensive variables are

  • Correct answer
    A
    $\mathrm{H}$ (Enthalpy)
  • B
    $p$ (Pressure)
  • Correct answer
    C
    E (internal energy)
  • Correct answer
    D
    $\vee$ (volume)

Solution

Among the given options, the e xtensive variables are $H$ (enthalpy), $E$ (internal energy). $V$ (volume).These variables have values that depends upon the quantity or size of matter present in the system. Other examples are heat capacity, entropy, free energy, length and mass.

Hence, the correct answer is options: 'A', 'C', 'D'.
