The internal energy U of a system is defined as the sum of the energies of all the constituent particles. The internal energy of an ideal gas does only depend on the temperature and the number of particles, and not on the volume occupied by the gas. Let us carry out an experience to confirm this statement.

Relation between internal energy and volume occupied
by a gas.
Considering the results of the previous experience choose one of the following options:
Given two ideal gases with the same type and number of particles, and at the same temperature,
An experience will be performed to help understanding the differences between the internal energy U and the temperature T of a system.
Comparison between two systems.
Two systems are shown made up of particles of the same mass. With the "CONTROL PANEL" we can control the number of particles and the energy of each system, and therefore its temperature.
If the systems possess the same internal energy U but different temperature T this is because
To make equal the temperature of two systems with the same internal energy but different number of particles,
