What is the change in internal energy for the system?
Understand the Problem
The question is asking for the change in internal energy for a system, which is a concept from thermodynamics. To find this, we typically use the first law of thermodynamics, which relates the change in internal energy to the heat added to the system and the work done by the system.
Answer
ΔU = q + w
The final answer is ΔU = q + w
Answer for screen readers
The final answer is ΔU = q + w
More Information
The first law of thermodynamics states that the change in internal energy (ΔU) of a system is equal to the heat (q) added to the system plus the work (w) done on the system. This forms the basis for understanding energy transformations in thermodynamic systems.
Tips
A common mistake is to not account for the sign conventions of heat and work; positive when entering the system and negative when leaving the system.
