- 0°C: melting point of pure ice
- 100°C: boiling point of pure water
- Temperatures below 0°C have negative values
Thermometers
- A device used to measure temperature
- Types of thermometers:
- Analog
- Digital
- Energy transfer known as heat occurs between objects at different temperatures
- Objects at the same temperature have the same average kinetic energy per particle
Temperature Conversions
- Absolute zero in °C: unknown
- Melting ice in °C: 0°C
- Boiling water in K: unknown
- Absolute zero in K: unknown
