of the sample.  --> THERMAL ENERGY

It doesn’t depend on

the size of the sample. --> TEMPERATURE

Explanation:

The temperature of a substance is a measure of the average kinetic energy of the particles in the substance.

In fact, the temperature is related to the average kinetic energy of the particles by:

where is the average kinetic energy, k is the Boltzmann constant, T is the absolute temperature of the substance.

Therefore, the temperature does not depend on the number of molecules in the substance.

The thermal energy of a substance instead is a measure of the total energy (kinetic+potential) of the particles in a substance: therefore, it also depends on the number of particles in the substance (the greater this number, the higher the thermal energy).

Therefore, the correct matchings are:
