Solution

Solution Steps

Step 1: Understanding Thermal Energy

Thermal energy is the total kinetic energy of particles in a substance due to their motion. It is a measure of the internal energy of a system and is associated with the temperature of the system.

Step 2: Identifying Types of Particle Motion

Particles in a substance can move in different ways, contributing to the thermal energy. The types of motion include:

Translational motion: Movement of particles from one place to another.
Rotational motion: Spinning of particles around an axis.
Vibrational motion: Oscillation of particles about a fixed position.

Step 3: Evaluating the Options

The question asks which types of motion contribute to thermal energy. Since thermal energy encompasses all forms of kinetic energy due to particle motion, all three types of motion (translational, rotational, and vibrational) contribute to thermal energy.

Final Answer

\(\boxed{\text{all of the above}}\)
