What does increasing the internal energy of a system typically result in?

Increasing the internal energy of a system generally results in a rise in temperature. Internal energy, which is the total energy contained within a system, is closely related to the temperature of the system. When energy is added to a system, it often manifests as an increase in kinetic energy of the particles within the system. This increase in kinetic energy raises the average velocity of the particles, resulting in a higher temperature.

In most systems, especially in ideal gases, there is a direct relationship between internal energy and temperature. Thus, when the internal energy increases—due to added heat or work done on the system—the thermal motion of particles enhances, leading to an increase in temperature. This principle underlies many processes in thermodynamics and is fundamental to understanding how energy transfer affects the state of matter.

Therefore, option C correctly reflects the relationship between internal energy and temperature.
