Based on the pV diagram, what process is it? (Hint: Figure 12.10) p (atm) 3 2 1 0 0 100 200 300 Selected Answer: Answers: V (cm³) adiabatic isothermal (constant temperature) any process isobaric (constant pressure) adiabatic isochoric (constant volume) If you mix food in a blender, the electric motor does work on the system, which consists of the food inside the container. This work can noticeably warm up the food. Suppose the blender motor runs at a power of 250 W for 40 s. During this time, 2000 J of heat flow from the now-warmer food to its cooler surroundings. Match the answers with questions.
