Can a body of larger mass be hotter than a body of smaller mass at the same temperature?

Yes, a body of larger mass can be hotter than a body of smaller mass if they are at the same temperature, but this typically refers to their thermal energy content rather than temperature alone. Temperature is a measure of the average kinetic energy of particles in a substance, and if both bodies are at the same temperature, they have the same average kinetic energy per particle, regardless of mass. However, the larger mass body will contain more total thermal energy due to its greater number of particles.
