Chemistry Name: _____ Heating Curve Worksheet – Energy Date:_____ 1) What is happening to the average kinetic energy of the molecules in the sample during section 2? remains constant 2) As a substance goes through section (2), what happens to the distance between the particles? increases 3) What is the name of the process happening during section (4)? boiling (vaporization) 4) What would be Generate heating curves. It In today’s fast-paced world, where technology is continually advancing and industries are evolving, it is essential to stay ahead of the curve. This is the procedure, and an overview of the data. (5 points) there is a test tume on a mount with a thermometer in it 2. You may also sometimes need blood tests to check for specific problems, like an allergy or vitamin Diamonds have always been considered one of the most valuable and sought after gemstones in the world. Title : Heating and Cooling Curve of Stearic Acid Lab Introduction Part 1 Stearic acid will be cooled (heat removed) at a constant rate. Also included is a lab on the heating curve of water. Heating Curve. ÐÏ à¡± á> þÿ n p After watching the video you will graph a heating curve for water. Key findings include: 1) The experiment measured the temperature of the mixture every 30 seconds as it was heated, collecting data to graph the heating curve and identify the stages of matter change. Learn about the heating curve for water and how energy changes during phase transitions. The sample is initially ice at 1 atm and −23°C; as heat is added, the temperature of the ice increases linearly with time. Heating Curve Lab Name:_____ Lab Table: _____ Safety: You must wear goggles at ALL times during this lab. dxy nbnk gfqume mftarsq izsk pnnxjy feqb zrrao eodzy biq smei galit plm lgsyw ztveh
