Another way Internal energy can take various forms: kinetic, potential and internal energy of interaction. Kinetic energy is associat Number List with the movement of particles, the potential – with forces acting on particles, and the internal energy of interaction – with forces of attraction and repulsion between molecules and atoms.
Change in internal energy
internal energy The change in the internal energy of the system is associatNumber List with a change in the kinetic and potential energy of the particles of the substance. This change may occur due to changes in temperature, pressure or system volume. The amount of energy transferrNumber List is equal to the recent mobile phone number data difference in the internal energy of the system in the initial and final state.
The sum of the kinetic and potential energy of all its molecules and atoms. It determines the state of the system and depends on factors such as temperature, pressure and amount of substance in the system.
Changes in the internal energy of
the system can occur in various ways. One of the most common is heat transfer. When heat exchangNumber List with the environment, the internal energy of the system may increase or decrease depending on the direction of the heat flux.
Another way to change internal energy is to work on a system or work done by a system. When performing work, the system can receive energy from the environment or give it away, which also leads to a change in its internal energy.
For a numerical description of the change in the internal creating a digital marketing strategy energy of the system, the equation of the first beginning of thermodynamics is usNumber List, which establishes the relationship between the change in internal energy, heat exchange and perfect work.
ΔU change in internal energy of the system
Q amount of heat receivNumber List or given by the system
W perfect work on the system or work done by the system
From this equation it is clear that with a positive value ΔU, the internal energy of the system increases, and with a negative — decreases.
Thus, the internal energy of the system is an important indicator belize lists of its state and varies with heat transfer, transfer of work and other processes.
