Study Notes
Unit 2: Chapter 6 - Thermal Energy
- Thermal energy is the sum of kinetic and potential energy of particles within a substance.
- Kinetic energy is the energy of motion, particles moving faster have more kinetic energy
- Potential energy is stored energy, based on the distance between particles
- Mechanical energy is the sum of the potential and kinetic energy of an object.
- In the example of a soccer ball, the potential energy depends on its distance from the Earth, while the kinetic energy is due to its movement.
Lesson 1: Thermal Energy, Temperature, and Heat
- Temperature is defined in terms of the average kinetic energy of particles in a material.
- Greater average kinetic energy equates to a higher temperature.
- Particles in warmer matter move more quickly on average, compared to particles in colder matter.
- Thermometers are used to measure temperature. Common scales include Celsius (°C), Kelvin (K), and Fahrenheit (°F).
- Heat is the transfer of thermal energy from a warmer object to a cooler object.
Temperature Conversion
- To convert Fahrenheit (°F) to Celsius (°C), use the formula: °C = (°F - 32) / 1.8
- To convert Celsius (°C) to Fahrenheit (°F), use the formula: °F = (°C x 1.8) + 32
