NEETChemistryThermodynamics (C)
Statement I : A molar property ( (X_m )= X n ) where ( X ) is the value of an extensive property. ( n ) is mole of matter, so ( X _ m ) is an intensive property. Statement II : An extensive property is a property whose value depends on quantity of matter.
Options
- ABoth statement I and statement II are incorrect.
- BStatement I is correct but statement II is incorrect
- CStatement I is incorrect but statement II is correct.
- DBoth statements I and statements II are correct.
Correct answer
C. Statement I is incorrect but statement II is correct.
Step-by-step solution
- Statement I: A molar property (X_m= ) is derived from an extensive property (X ), but it becomes intensive when divided by the number of moles (n ). The statement claims this correctly, but the phrasing about intensive property is confusing and misleading, making it incorrect in its formulation. - Statement II: An extensive property is indeed one that depends on the quantity of matter (e.g., mass, volume, energy), which is correct.
