The change would be 100 joules, because an isochoric system can not perform the work.

An isobaric process is a thermodynamic-processin which the pressure stays constant: Δp = 0 The term derives from the Greek isos, meaning "equal," and barus, "heavy." The heat transferred to the system does work but also changes the internal energy of the system:
The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)
If a thermodynamic process takes place at a constant temperature it is called "isothermal". A word of caution however: the internal energy of a system may not remain the same in an isothermal process if the composition or phase changes; e.g. melting ice can be an isodthermal process but there is certainly a change in internal energy when it happens.
because in adiabatic process heat absorbed is zero. and the work is done by internal energy. so internal energy decreases.we know that temperature is directly related with internal energy

Since internal energy is a state function and a cyclic process always returns to the same state (that's how you define a cyclic process), the value of the the internal energy will remain constant. That is not to say that it doesn't change along the cyclic path during the process - just that it always returns to the same value when the cycle is complete.
The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.
If a thermodynamic process takes place at a constant temperature it is called "isothermal".

Yes, if the process is occurring under an isothermal condition where change in T=0

into internal energy
Energy content of the molecules of gas decreases. Energy of the system remains same. But it depends on what the conditions are too. Depends on the process of conversion: If it's isobaric, then decreases If it's isochoric, then decreases If it's isothermal, then increases If it's adiabatic, then no change
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
Potential energy and internal energy are different things and unrelated - except when a process converts one to the other. In most processes involving gases, the density of the gas is so low that changes in potential energy (which depend on total mass times change in height) are not significant in comparison to changes in the internal energy, so we neglect it in out calculations.
It is change in internal energy. If the volume of the system remains unchanged (isochoric process)then the heat given to the system is entirely utilized to increase the internal energy of that system. It is to be noted that no pressure-voulme work is done in such processes.
