Question

Select the correct answer.

Answer 1

Answer:

A.  it is the lowest at low temperatures

B.  it increases at low temperatures

C.  it is the same at all temperatures

D.  it is the lowest at high temperatures

Answer 2

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
