Question

The motion of particles is because of their , which with rising temperature.

• A. potential energy
• B. kinetic energy
• C. increases
• D. decreases
• E. remains unaffected

Answer 1

Answer: (B), (C)

increases

"Kinetic" means relating to the motion. So, the motion of particles is associated with their kinetic energy. As the energy is given to the particles in the form of heat, the kinetic energy of particles increases and the particles start moving faster. Thus, the kinetic energy of particles increases with the increasing temperature.
