Answer:
A. it is the lowest at low temperatures
Explanation:
It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.
The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.
- Kinetic energy is directly proportional to the temperature of a substance.
- The higher the temperature, the more the kinetic energy of the molecules within a system.
- At low temperature, kinetic energy is the lowest.
- At the highest temperature, kinetic energy is the highest
Colligative properties include lowering the freezing point, lowering the vapor pressure, and raising the boiling point.
