Question

Determine whether the descriptions represent radiation, conduction, or convection.
Description Radiation Conduction Convection
Thermal energy is transferred from particle to particle



Some sunlight is reflected off into space



Warm water rises, cold water sinks



Sunlight travels through space to Earth



Warm air rises, cold air sinks



Heat energy is transferred between particle contact

Answer 1

Here’s how to categorize each description based on radiation, conduction, or convection:

1. **Thermal energy is transferred from particle to particle**
- **Conduction**

2. **Some sunlight is reflected off into space**
- **Radiation**

3. **Warm water rises, cold water sinks**
- **Convection**

4. **Sunlight travels through space to Earth**
- **Radiation**

5. **Warm air rises, cold air sinks**
- **Convection**

6. **Heat energy is transferred between particle contact**
- **Conduction**

Summary:
- Conduction: 1, 6
- Radiation: 2, 4
- Convection: 3, 5
