NEET Chemistry First Law MCQ Question
Which of the following combinations correctly represent the implications of the First Law of Thermodynamics?
The internal energy change depends only on the initial and final states, and energy can neither be created nor destroyed.
Heat transfer and work done are always equal, leading to zero change in internal energy.
An isolated system allows for energy creation from work, resulting in increased internal energy.
The First Law implies that all processes converting heat to work are 100% efficient.
Correct Answer
Detailed Explanation
According to the First Law of Thermodynamics, the change in internal energy depends only on the initial and final states of the system, and it asserts the principle of conservation of energy, meaning energy can neither be created nor destroyed.
