Experiment 1: Heat FlowIn this experiment, you will investigate the Second Law of Thermodynamics using heat flow.MaterialsPermanent Marker3 Styrofoam® Cups*Ice*Water (Cold, Room Temperature and Hot)**Microwave **Microwave Safe Container*You Must Provide*Only Necessary If Hot water Source Is Not AvailableProcedure1. Use the permanent marker to label one of the Styrofoam® cups “Ice Water” and fill it with ice and water. 2. Use the permanent marker to label a second Styrofoam® cup “Room Temperature” and fill it with room temperature water. Allow the cup to rest for five minutes to reachroom temperature. 3. Use the permanent marker to label the last Styrofoam® cup “Hot Water” and fill it with hot water from a sink or tap. If a hot water source is not available use a microwave and microwave safe container to heat water for twenty seconds.LAB SAFETY: Do not make the hot water too hot because you will be putting your finger in the water to make qualitative observations. 4. Put one finger into the “Hot Water” cup for thirty seconds and then immediately place it in the “Room Temperature” cup. Record your observations in Post-Lab Question 1. 5. Put one finger into the “Ice Water” cup for thirty seconds and then immediately placeit in the “Room Temperature” cup. Record your observations in Post-Lab Question 2.Post-Lab Questions© 2014 eScience Labs, LLC.All Rights Reserved1. Describe the feeling you experienced when you placed your finger in the room temperature water after it was in the warm water.2. Describe the feeling you experienced when you placed your finger in the room temperature water after it was in the ice water.3. After you put your finger in the room temperature water, describe the flow of heat forthe finger that was originally in the hot water. 4. After you put your finger in the room temperature water, describe the flow of heat forthe finger that was originally in the cold water. 5. According to the Second Law of Thermodynamics, your finger will not gain the heat it lost once you put it into the room temperature water, but eventually your hand does warm back up.
