Which of the following is NOT a form of kinetic energy?

• A. When the temperature of a substance rises causing the molecules of that substance to move faster.
• B. When a hockey puck slides across the ice after being hit by a player.
• C. When glucose molecules are broken down to create energy for cellular work.
• D. When the molecules of the air vibrate transmitting soundwaves.

Answer: (C)

Verified step by step guidance

1. Understand the concept of kinetic energy: Kinetic energy is the energy of motion. It is associated with objects or particles that are moving.
2. Analyze each option to determine if it involves motion: For each scenario, consider whether it involves movement or motion of particles or objects.
3. Option 1: When the temperature of a substance rises, the molecules move faster. This is a form of kinetic energy because the molecules are in motion.
4. Option 2: When a hockey puck slides across the ice, it is moving. This is a form of kinetic energy because the puck is in motion.
5. Option 3: When glucose molecules are broken down to create energy, this process involves chemical energy, not kinetic energy. The breakdown of glucose is a chemical reaction that releases energy for cellular work, but it does not involve motion of the molecules themselves as kinetic energy does.
