When the particles of a substance move faster, the temperature of that substance generally increases. Temperature is a measure of the average kinetic energy of the particles in a substance; as the kinetic energy increases due to faster particle movement, the temperature rises.
### Difference between Temperature and Thermal Energy:
1. **Temperature**:
- Temperature is a measure of the average kinetic energy of the particles in a substance.
- It is an intensive property, meaning it does not depend on the amount of substance present.
- Measured in degrees Celsius (°C), Kelvin (K), or Fahrenheit (°F).
2. **Thermal Energy**:
- Thermal energy refers to the total internal energy of a substance due to both the kinetic energy of its particles and the potential energy of their interactions.
- It is an extensive property, meaning it depends on the amount of substance present.
- Thermal energy increases with both the temperature and the quantity of the substance (e.g., mass or volume).
In summary, while temperature indicates how hot or cold a substance is (and reflects the average motion of its particles), thermal energy accounts for the total energy contained within a system, which includes contributions from all particles.
