Experiment 1 Heat Flow In this experiment you will investigate the Second Law of Thermodynamics using heat flow Materials Permanent Marker 3 Styrofoam Cups Ice Water Cold Room Temperature and Hot Microwave Microwave Safe Container You Must Provide Only Necessary If Hot water Source Is Not Available Procedure 1 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 reach room 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 place it in the Room Temperature cup Record your observations in Post Lab Question 2 Post Lab Questions 2014 eScience Labs LLC All Rights Reserved 1 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 for the finger that was originally in the hot water 4 After you put your finger in the room temperature water describe the flow of heat for the 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 Why 2014 eScience Labs LLC All Rights Reserved
