Michigan Merit Exam: Energy Transfer & Conservation Objectives
The Michigan Merit Exam is a three-part test consisting of: the ACT Plus Writing exam, three sections of the ACT WorkKeys exam, and a test developed by the state of Michigan called the M-Step. The exam is given each spring to assess the academic achievement of 11th grade students in Michigan's public schools. This study chapter is relevant to the M-Step and ACT Plus Writing tests because they both contain questions about chemistry. The ACT science session is an on-paper test that is timed at 35 minutes and consists of 40 multiple-choice questions. The 50-minute-long M-Step is computer-delivered.
1. The Kinetic Molecular Theory: Properties of Solids and Liquids
This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.
2. The Kinetic Molecular Theory: Properties of Gases
What makes a gas ideal? What types of characteristics do ideal gases have? In this lesson, we will discuss the many characteristics of gases and how knowing the microscopic properties of gas particles will help you understand the macroscopic properties of a gas.
3. Changes in Heat and Energy Diagrams
Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.
4. Phase Changes and Heating Curves
Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.
5. Endothermic and Exothermic Reactions
Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
