NEET Physics Heat Engines MCQ Question
What is the relationship between work done on a system and the change in internal energy, according to J. P. Joule's experiments?
The work done determines the change in internal energy regardless of the method.
Work done only affects internal energy in adiabatic processes.
The internal energy change is independent of the work done on the system.
Only electrical work affects the internal energy of a system.
Correct Answer
Detailed Explanation
J. P. Joule's experiments demonstrated that the change in internal energy is directly related to the work done on the system, irrespective of how the work is performed.
