Which form of energy is associated with the random motion of particles in a gas?

• A. Potential energy
• B. Electrical energy
• C. Chemical energy
• D. Thermal energy

Answer: (D)

Verified step by step guidance

1. Understand that energy can exist in various forms, such as potential energy, electrical energy, chemical energy, and thermal energy.
2. Recall that the random motion of particles in a gas refers to the kinetic activity of those particles moving in all directions with varying speeds.
3. Recognize that thermal energy is the form of energy related to the temperature of a substance, which arises from the kinetic energy of the random motion of its particles.
4. Differentiate thermal energy from potential energy (energy stored due to position), electrical energy (energy from electric charges), and chemical energy (energy stored in chemical bonds).
5. Conclude that the energy associated with the random motion of particles in a gas is thermal energy, as it directly relates to the kinetic energy of those particles.
