It means that 2/3 of the work done on the system has escaped the system as heat flow.Anonymous119 said:Ok, if it says that change of internal energy is part(for example 1/3) of TOTAL work executed over system(body). Does it mean that is TOTAL work indeed sums of every single work(mechanical work+internal energy change+...) ?
The concept of work is the transfer of energy from one system to another. Total work is the sum of all external forces acting on a system, while internal energy change is the change in energy within a system due to its internal processes. Therefore, work equals the sum of both external and internal energy changes.
Work can be calculated by multiplying the force applied to a system by the displacement of the system in the direction of the force. It can also be calculated by adding the changes in internal energy and total work together.
The relationship between work, total work, and internal energy change is that work is the sum of both total work and internal energy change. In other words, work is the combined effect of both external and internal forces on a system.
The concept of work can be applied to various systems, including mechanical, electrical, and chemical systems. In each of these systems, work is the transfer of energy from one form to another, and the total work and internal energy change may vary depending on the specific system and its processes.
Yes, the work done on a system can be negative. This can happen when the force applied to the system is in the opposite direction of the displacement, resulting in a negative value for work. This means that energy is being transferred out of the system, and the system is performing work on its surroundings.
