Physical Science B Unit 4: Thermal Energy Sample Work

Physical Science B Unit 4: Thermal Energy Sample Work Physical Science B Unit 4: Thermal Energy Sample Work Instructions You will be required to complete sample work for this and every unit of physical science. Complete the notes and graphic organizers below to help you understand and process what you are reading in the lessons. Click on “view” from the menu above, then click on “Show document outline.” You can use the document outline to advance to the lesson you are working on. You will need to make a copy of this document in order to write on it - Select the FILE menu, then Download to get a MS Word document. Or, click the FILE menu, then Make a Copy to make a Google Docs copy of the document. At the end of the unit, in the review lesson, there will be a dropbox to submit your sample work. ● This is where you will submit your completed work. ● If you selected FILE → DOWNLOAD and completed this as a Word document, you can just upload that. ● If you selected FILE → MAKE A COPY and completed this in google drive, you will need to make a pdf of this file. Click on the File menu, select “Download as” and choose “PDF document (.pdf). ● Rename the document with your last name and “unit _ sample work” Lesson 1: Kinetic and Thermal Energy Key Words ● kinetic energy — energy of motion ● potential energy — stored energy that depends upon an object’s position ● temperature — a measure of the average kinetic energy of particles ● thermal energy — describes the total energy of a group of particles Questions Pages 1, 2, 3 of the lesson are just an introduction of what is to come. You can read over these pages, but do not need to take notes or answer questions about the pages. Question Answer 1. What specific type of kinetic energy is Thermal Energyfound in the atoms or molecules of every piece of matter? 2. The average kinetic energy of a substance is described by what term? Temperature 3. Where is the potential energy found in all matter? Where is it stored? In the bonds of atoms and molecules 4. There are three scales used in science to measure temperature. Complete the chart below to compare the three scales Fahrenheit Celsius Kelvin Boiling point of water 212 Degrees 100 Degrees 373.1 K Freezing point of water 32 Degrees 0 Degrees 273.1 K Conversion formula C=5/9X(F-32) F=(CX9/5)+32 K = ℃ + 273.15 Where used? United States and its territories The rest of the world and the medical world. Low temperatures in science labs Side note: Most people use technology to convert between the temperature scales, so being able to use the formula and converting will not be explored in this class. 5. What is the difference between thermal energy and temperature? Well, temperature is a measure of the average kinetic energy of particles. The higher the temperature, the higher the kinetic energy. Thermal energy also includes the potential energy, which relates to the distance between particles and their freedom to move around. 6. A B Which model above represents a solid? Which one represents a liquid? How do you know? Model A Because the particles aren't moving 7. The potential energy of the particles in both ice and water is related to the Ice has more potential energy then water
