When mechanical work is done, the internal energy of a system can change. If work is done on the system, the internal energy increases. Conversely, if work is done by the system, the internal energy decreases. This change in internal energy is governed by the first law of thermodynamics.
When work is done on a system, its internal energy increases. This is because the work done transfers energy to the system, raising the energy of its particles and increasing their kinetic and potential energies.
Heat, work, and internal energy are all forms of energy transfer. Heat is energy transfer due to a temperature difference, work is energy transfer due to a force acting through a distance, and internal energy is the total energy of a system. The change in internal energy of a system is the sum of the heat added to the system and the work done on the system.
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
When work is done on a system by pushing it, the internal energy of the system increases, leading to an increase in temperature. The work done increases the kinetic energy of the particles in the system, causing them to move faster and leading to an increase in temperature.

When mechanical work is done on a system, there is an increase in the system's internal energy. This increase in internal energy is due to the transfer of energy from the mechanical work applied to the system.

The change in internal energy of a system is the sum of the heat added to the system and the work done on the system.
If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.

The change in internal energy of a system that does 100 joules of work depends on the heat exchange as well. In general, the change in internal energy is equal to the amount of heat added to the system minus the work done by the system.
In an adiabatic process, the work done is equal to the change in internal energy of a system.
the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.
The internal energy of a system increases when energy is added to the system through heat transfer or work done on the system. This can result in an increase in temperature, change in phase, or other forms of internal energy change.
