Answer:
Yes
Step-by-step explanation:
Yes, it is possible for the internal energy of a system to be greater than the kinetic energy of the molecules and atoms making up the system.
Internal energy is the sum of all forms of energy within a system, including kinetic energy, potential energy, and thermal energy due to the motion and interaction of particles within the system. The kinetic energy of the molecules and atoms making up the system is just one component of the internal energy.
For example, if a system is at high pressure and temperature, the internal energy of the system can be dominated by the thermal energy due to the random motion and collisions of particles within the system, even if the kinetic energy of each individual particle is relatively low. In this case, other forms of internal energy such as potential energy due to intermolecular forces or chemical bonds may also contribute significantly to the total internal energy of the system.
Therefore, the internal energy of a system is not solely dependent on the kinetic energy of the particles making up the system, and it is possible for the internal energy of a system to be greater than the kinetic energy of its constituent particles.
