हिन्दीGiven below are two statements:\n Statement I: The heat absorbed by a system at constant volume is equal to the change in its internal energy (\( q_v = \Delta U \)).\n Statement II: The heat absorbed by a system at constant pressure is equal to the change in its enthalpy (\( q_p = \Delta H \)). \nIn the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 1
Both Statement I and Statement II are correct.
Explanation
By definition from first law of thermodynamics, at constant volume \( w = 0 \implies q_v = \Delta U \), and at constant pressure \( q_p = \Delta H \). Both statements are correct.
