An isochoric process is one in which the volume is held constant (V=constant), meaning that the work done by the system will be zero. It follows that, for the simple system of two dimensions, any heat energy transferred to the system externally will be absorbed as internal energy.
An isochoric process is also known as an isometric process or an isovolumetric process. An example would be to place a closed tin can containing only air into a fire. To a first approximation, the can will not expand, and the only change will be that the gas gains internal energy, as evidenced by its increase in temperature and pressure. Mathematically, δQ = dU. We may say that the system is dynamically insulated, by a rigid boundary, from the environment.

Explanation:
An isochoric process, also known as a constant volume process, is a thermodynamic process where the volume of the system remains constant. This means that no work is done by or on the system. Therefore, the internal energy change in an isochoric process is solely due to the heat absorbed or released by the system.
Option A: Equal to the heat absorbed.
This option is correct because in an isochoric process, the internal energy change is solely due to the heat absorbed by the system. Therefore, the increase in internal energy is equal to the heat absorbed.
Option B: Equal to heat evolved.
This option is incorrect because in an isochoric process, no heat is evolved. The internal energy change is solely due to the heat absorbed by the system.
Option C: Equal to the work done.
This option is incorrect because in an isochoric process, no work is done. The volume of the system remains constant, so no work is done by or on the system.
Option D: Equal to sum of heat absorbed and work done.
This option is incorrect because in an isochoric process, no work is done. Therefore, the internal energy change is solely due to the heat absorbed by the system.

Isochoric Process and Internal Energy
Isochoric Process:
An isochoric process is a thermodynamic process in which the volume of the system remains constant, and no work is done by or on the system. In other words, the system is kept at a constant volume.
Internal Energy:
Internal energy is the sum of all the kinetic and potential energies of the molecules in a system. It is a state function, which means that it depends only on the present state of the system and not on how the system arrived at that state.
Increased Internal Energy:
During an isochoric process, the internal energy of the system increases. This increase in internal energy can be due to the absorption of heat by the system from the surroundings or due to some other process that increases the internal energy without any exchange of heat with the surroundings.
Answer:
The correct answer is option 'A' - the increased internal energy is equal to the heat absorbed. This is because an isochoric process does not involve any work done, so the change in internal energy is due solely to the heat absorbed by the system.
Therefore, during an isochoric process, any increase in internal energy is due to the heat absorbed by the system.
