Study Notes
Heat Transfer
- Heat is energy transferred from one body to another, resulting from a temperature difference.
- Temperature is a measure of the average kinetic energy of the particles in a substance.
Methods of Heat Transfer
- Conduction: Heat energy is transferred from particle to particle until the entire object reaches a uniform temperature. This process is often seen with materials capable of directly touching each other.
- Convection: Heat energy travels through fluids (liquids or gases) by movement of the fluid itself. Warm fluids rise, and cool fluids sink creating a cyclical pattern.
- Radiation: Heat travels through space or other materials without direct contact. This often occurs in the form of electromagnetic waves or particles.
Temperature Scales
- Celsius (C): A temperature scale where 0°C is the freezing point of water and 100°C is the boiling point of water.
- Fahrenheit (F): A temperature scale in which 32°F is the freezing point of water and 212°F is the boiling point of water.
- Kelvin (K): A temperature scale referenced from absolute zero where no kinetic energy remains. 0K is the reference point, absolute zero, where there is no particle motion. 273.15 K is equal to 0 °C
