Answer:
B. move more quickly
Explanation:
As a sample of matter is heated, we know that the particles begins to move more quickly.
This is because the temperature of a substance is directly proportional to the average kinetic energy of a system.
- As the temperature increases, the body gains more kinetic energy
- This is translated to the particles of the medium.
- Then they begin to move quickly and very fast enough.
