The image shows a classroom setting, likely in Jiangning District, China. A chalkboard displays the text "Homework 5", with the problem "(1) Prove ΔU = -W by using conservation of me." The word "partial" is also written on the board. A person in a light blue shirt stands near the chalkboard. Part of a projector screen is visible at the bottom of the frame, showing a diagram. To the left, a ceiling fan hangs. Several students are partially visible on the right.
