Gizmo: Week 1 Online Calorimetry Lab - 2021 l Week 1 Online Calorimetry Lab Gizmo 2021

Week 1 Online Lab: Calorimetry Lab Gizmo Explore Learning Gizmo: Calorimetry Lab For this assignment, you'll use a Gizmo at the Explore Learning web site. Before you begin: • Be sure you have read the assigned reading for the week. • You may want to print this document so that you can note observations as you work with the gizmo. Later, you can type your answers into the Word document and upload it with this assignment form. • All questions to answer are contained in this document. You don’t need to answer any questions at the Explore Learning site. • This lab has a Prior Knowledge piece, a Warm-Up piece, and Activity A, B, & C and an extra credit opportunity. • You must answer in a different colored font (-1 point) FINDING THE GIZMO Follow these steps to find the Gizmo: • Go to the Explore Learning website: • If you have not yet enrolled in the class -- In the upper right hand corner, click on Enroll in a Class. • The class code you need is 6FZRUV6SEM (note - these are all capital letters). • Click on Continue. • If you have used the Explore Learning site before you should be able to log in using your MNOHS username and password (for example, mnohs10ajones / piano227). If you have never used Explore Learning before, you’ll need to register using your MNOHS username and password with the class code. In other words, the class code is only needed once! • Once inside the Physics course, look for the Gizmo called Calorimetry Lab and click on Launch Gizmo. Vocabulary: calorie, calorimeter, joule, specific heat capacity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. The Latin word calor means “heat,” and meter comes from the Greek word meaning “to measure.” What do you think a calorimeter does? It can be used to find a substance heat capacity 2. Where have you heard the word calorie before? What do you think a calorie is? I’ve heard calorie before in terms of food and stuff but in this instance I’m pretty sure it’s meaning about a temperature heat capacity Gizmo Warm-up A calorimeter is an insulated container filled with a liquid, usually water. When a hot object is placed in the calorimeter, heat energy is transferred from the object to the water and the water heats up. Calorimeters can be used to find a substance’s specific heat capacity. You will use the Calorimetry Lab Gizmo to determine the specific heat capacities of various substances. 1. On the SIMULATION pane, select Copper. Use the slider to set its Mass to 200 g. Set the Water mass to 200 g. Check that the Water temp is set to 30.0 °C and the copper’s Temp is 90 °C. Select the GRAPH tab, and click Play ( ). A. What was the Final temperature of the copper and the water? The final temperature was 34.95c_ B. How much did the temperature of the copper change? The copper temperature changed by 55.05c C. How much did the temperature of the water change? the water changed by 4.96c 2. Specific heat capacity can be described as a substance’s resistance to temperature changes. Which substance has a greater specific heat capacity, copper or water? Explain.
