Final answer:
The claim is false. At the same temperature, all particles have the same average kinetic energy. So, lighter particles like gas molecules tend to move faster than heavier ones.
Step-by-step explanation:
The statement that heavier (larger) particles move faster than lighter (smaller) particles at the same temperature is false. This question relates to the principles of kinetic theory, specifically the energy of particles in motion. At a given temperature, all particles, regardless of their size, have the same average kinetic energy. Therefore, it's actually the smaller, lighter particles that generally move faster because a larger particle requires more energy to move at the same speed as a smaller one. This is evident, for example, in a gas, where lighter molecules like helium move faster than heavier molecules like oxygen at the same temperature.
