Describe how energy flows between the room temperature water and the cold hand at the molecular level.
How will the amount of thermal energy change for the hot hand when placed in the room temperature water?
How will the temperature change for the hot hand when placed in the room temperature water?
How will the amount of thermal energy change for the cold hand when placed in the room temperature water?
How will the temperature change for the cold hand when placed in the room temperature water?
1. Add arrows to the model below to show the flow of thermal energy into/out of the hot and cold hands.
2. The system boundary is the edge of the hands. Use the typing tool to list the inputs and outputs for the hot hand system and the cold hand system.
