1,000 J
The internal energy change of the system would be the sum of the heat absorbed and the work done on the system. Therefore, the internal energy change would be 20000 J (heat absorbed) + 5000 J (work done) = 25000 J.
400 joules.
A certain system absorbs 350joules of heart and has 230joules of work done on it. What is the value of Delta?
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.
The change would be 100 joules, because an isochoric system can not perform the work.

-70 Joules
The change would be 100 joules, because an isochoric system can not perform the work.
The total energy added to the system is 160 Joules, comprising of 100 Joules of heat and 60 Joules of work. This increase in energy will lead to a rise in the system's internal energy.
The internal energy change of the system can be calculated by subtracting the work done by the system from the heat added to the system. In this case, the internal energy change is ΔU = Q - W = 850 J - 382 J = 468 J. Therefore, the internal energy of the system increases by 468 Joules.
The temperature of graphite will increase because it absorbs thermal energy. The temperature increase can be calculated using the specific heat capacity of graphite.
The change in internal energy can be calculated as the sum of the work done and heat added to the system. The work done is already in Joules, so we need to convert the heat added from calories to Joules: 200 cal = 837.4 J. Thus, the change in internal energy is 1200 J + 837.4 J = 2037.4 J.
The relation between joules and kelvin is in the context of energy and temperature. For an ideal gas, the change in internal energy of a system can be related to temperature change in Kelvin using the specific heat capacity of the substance. This relationship is given by the equation ΔU = nCvΔT, where ΔU is the change in internal energy in joules, n is the number of moles of gas, Cv is the molar specific heat capacity at constant volume, and ΔT is the temperature change in Kelvin.
To convert Joules to kilocalories, divide the amount of energy in Joules by 4184 (the conversion factor between Joules and kilocalories). Thus, 263 Joules is equivalent to approximately 0.063 kcal.
