Which one of the following statement bolds good for the equation dQ=dE...
Explanation:
The given equation dQ=dE-dW represents the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

Option A: Any process undergone by a closed stationary system
This statement is incorrect because the equation is applicable to all types of systems, not just closed stationary systems.

Option B: Any process, reversible and irreversible and for any system
This statement is correct because the equation is valid for both reversible and irreversible processes and any type of system, whether open, closed, or isolated.

Option C: A closed system when only pdV work is present
This statement is incorrect because the equation is applicable to all types of work, not just pdV work.

Option D: Only reversible process
This statement is incorrect because the equation is valid for both reversible and irreversible processes.

Therefore, the correct answer is option B, which states that the equation dQ=dE-dW is applicable to any process, reversible and irreversible, and for any system.
