Question
If the amount of work done (W) is the same as the amount of energy transferred in by heat (Q), the net change in internal energy is 1
Solution
The statement you provided is related to the first law of thermodynamics, which states that the change in internal energy (∆U) of a system is equal to the heat added to the system (Q) minus the work done by the system (W). Mathematically, it is represented as:
∆U = Q - W
If the amount of work done (W) is the same as the amount of energy transferred in by heat (Q), then the equation becomes:
∆U = Q - Q
This simplifies to:
∆U = 0
So, if the work done is equal to the heat added, the net change in internal energy of the system is zero, not 1.
