Scalar quantities are those that have magnitude only and do not have a direction. Among the options you've provided:
1. **Force and energy** - Force is a vector (has both magnitude and direction), while energy is a scalar.
2. **Distance and displacement** - Distance is a scalar (only has magnitude), while displacement is a vector (has both magnitude and direction).
3. **Speed and velocity** - Speed is a scalar (only has magnitude), while velocity is a vector (has both magnitude and direction).
4. **Time and temperature** - Both time and temperature are scalar quantities.
Therefore, the quantities that are scalar are **time and temperature**.
1. **Force and energy** - Force is a vector (has both magnitude and direction), while energy is a scalar.
2. **Distance and displacement** - Distance is a scalar (only has magnitude), while displacement is a vector (has both magnitude and direction).
3. **Speed and velocity** - Speed is a scalar (only has magnitude), while velocity is a vector (has both magnitude and direction).
4. **Time and temperature** - Both time and temperature are scalar quantities.
Therefore, the quantities that are scalar are **time and temperature**.
