Unit 2 Chapter 6: Thermal Energy Lesson 1: Thermal Energy, Temperature, and Heat Kinetic and Potential Energy Potential energy is stored energy due to the interaction between two object. The potential energy plus the kinetic energy of an object is the mechanical energy of the object. Lesson 1: Thermal Energy, Temperature, and Heat What is thermal energy? Every solid, liquid, and gas is made up of trillions of tiny particles that are constantly moving. Because particles are in motion, they have kinetic energy. The faster particles move, the more kinetic energy they have. Lesson 1: Thermal Energy, Temperature, and Heat What is thermal energy? The greater the average distance between particles, the greater the potential energy of the particles. Thermal energy is the sum of the kinetic energy and the potential energy of the particles that make up a material. Lesson 1: Thermal Energy, Temperature, and Heat The potential energy of the soccer ball depends on the distance between the ball and Earth. The potential energy of the particles of matter depends on their distance from one another. Lesson 1: Thermal Energy, Temperature, and Heat What is thermal energy? Mechanical energy describes the energy of one object. Thermal energy describes the energy of the particles that make up a solid, liquid, or gas. Lesson 1: Thermal Energy, Temperature, and Heat What is temperature? Scientists define temperature in terms of kinetic energy. Temperature represents the average kinetic energy of the particles that make up a material. Lesson 1: Thermal Energy, Temperature, and Heat What is temperature? The greater the average kinetic energy of particles, the greater the temperature. The particles in warmer air move at a greater average speed than the particles in colder air. Lesson 1: Thermal Energy, Temperature, and Heat Key Concept Check How are temperature and kinetic energy related? Lesson 1: Thermal Energy, Temperature, and Heat What is temperature? Temperature and thermal energy are related, but they are not the same. The particles that make up liquid and solid water have different potential energies, and therefore, different thermal energies. Lesson 1: Thermal Energy, Temperature, and Heat What is temperature? Thermometers are used to measure temperature. Common temperature scales are Celsius (℃), Kelvin (K), and Fahrenheit (℉) Lesson 1: Thermal Energy, Temperature, and Heat Converting Between Temperature Scales - To convert Fahrenheit to Celsius, use the following equation: ℃ = (℉ - 32) / 1.8 Lesson 1: Thermal Energy, Temperature, and Heat Converting Between Temperature Scales - To convert Celsius to Fahrenheit, use the following equation: ℉ = (℃ x 1.8) + 32 Lesson 1: Thermal Energy, Temperature, and Heat ASK: Convert 176 ℉ to Celsius. Lesson 1: Thermal Energy, Temperature, and Heat ASK: Convert 37 ℃ to Fahrenheit. Lesson 1: Thermal Energy, Temperature, and Heat What is heat? The movement of thermal energy from a warmer object to a cooler object is called heat. All objects have thermal energy; however, you heat something when thermal energy transfers from one object to another. The rate at which heating occurs depends on the difference in temperatures between the objects. Lesson 1: Thermal Energy, Temperature, and Heat Key Concept Check How do heat and thermal energy differ? Lesson 1: Thermal Energy, Temperature, and Heat HW Complete Chapter 6.1 Lecture Notes and submit it on Canvas Complete Chapter 6.1 Worksheet and submit it on Canvas
