Describe the photo of the tea kettle at the beginning of this section in terms of heat transfer, work done, and internal energy. How is heat being transferred? What is the work done and what is doing it? How does the kettle maintain its internal energy?
Step 1 of 2
From the first law of thermodynamics, the heat is supplied to the system Q causes change in internal energy of the system ΔU and system may do some work W.
Q = ΔU + W
