The temperatures of equal amounts of different substanceschange differently as they are heated or cooled. In this lab you willdetermine how the temperatures of two different materials change asthey absorb and release heat.Procedure1. Design two data tables to record your temperature measurementsof the hot- and cold-water beakers. Use the sample table to help you.2. Pour 200 mL of hot tap water (about 90°C) into each of twolarge beakers.3. Pour 200 mL of cool tap water into each of two large beakers. Addtwo or three ice cubes and stir until the ice melts.Safety PrecautionsWARNING: Use care whenhandling the heated bagsand hot water. Do not taste,eat, or drink any materialsused in the lab. Take carewhen handling glassthermometers.184 CHAPTER 6 EnergyKS Studios
