Calorimetry: Practice Problem & Solution

Consider the following statements: A. The temperature at which the liquid and solid state of substance is in thermal equilibrium with each other is called its melting point. B. The temperature at which the liquid and the vapour states of the substance coexist is called its boiling point. C. The change from solid state to vapour state without passing through liquid state is called sublimation. Based on above information pick correct option.
Only A and B correct
Only C and B are correct
Only C is incorrect
All statements A, B and C are correct

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Calorimetry. Understanding the underlying formula is key to arriving at the correct answer below:

All statements correctly define physical principles: statement A defines melting point, statement B defines boiling point, and statement C defines sublimation.
