### a) List of Scalars
Scalars are quantities that are fully described by a magnitude alone (a numerical value) and do not have a direction. Some specific examples of scalars include:

1. **Temperature**: 25 degrees Celsius
2. **Mass**: 10 kilograms
3. **Time**: 5 seconds
4. **Speed**: 60 kilometers per hour (not velocity)
5. **Energy**: 100 joules
6. **Distance**: 10 meters

### b) List of Vectors
Vectors are quantities that require both a magnitude and a direction for a complete description. Some specific examples of vectors include:

1. **Displacement**: 10 meters to the north
2. **Velocity**: 60 kilometers per hour to the east
3. **Acceleration**: 9.8 meters per second squared downward
4. **Force**: 15 newtons at an angle of 30 degrees from the horizontal
5. **Momentum**: 5 kg·m/s to the west

### What Makes These Scalars?
Scalars are characterized by the following attributes:
- **Magnitude Only**: Scalars are described solely by a numerical value (magnitude) without requiring any additional information about direction.
- **Single Dimension**: A scalar can be fully represented in one dimension (e.g., just a number).

### What Makes These Vectors?
Vectors have certain characteristics that distinguish them from scalars:
- **Magnitude and Direction**: Vectors are described by both a magnitude and a direction. For instance, saying "10 meters" as a scalar is different from saying "10 meters to the north" as a vector.
- **Multi-Dimensional Representation**: Vectors can involve multiple dimensions (e.g., a vector in two-dimensional space requires an x and y component).

In summary, the key distinction between scalars and vectors is that scalars have only magnitude, while vectors include both magnitude and direction.
