हिन्दीConsider the following statements regarding thermodynamic variables: (A) Pressure (\( p \)), volume (\( V \)), and temperature (\( T \)) are state variables. (B) The values of state functions depend only on the initial and final states of the system. (C) Heat (\( q \)) and work (\( w \)) are state functions. (D) The absolute value of the internal energy of a system can be readily determined by simple physical measurements. Which of the above statements are correct?
Correct answer · Option 2
(A) and (B) only
Explanation
Statements (A) and (B) are correct. (C) is incorrect because q and w are path functions. (D) is incorrect because the absolute value of internal energy cannot be determined, only changes (\( \Delta U \)) can be measured.
