internal energy change in words is the difference between the added energy and the original energy 100 - 60 = 40J
The work done by the system can be calculated by finding the difference between the heat absorbed from the high-temperature reservoir and the heat passed onto the low-temperature reservoir. In this case, the work done by the system is 130 joules (425 joules - 295 joules).
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 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.
The heat generated by 1700 joules of work depends on the efficiency of the process. In an ideal case where all the work is converted into heat, the heat generated would also be 1700 joules. However, in real-world scenarios, the heat generated would be less due to energy losses.
To calculate the work done by the system, we can use the formula for efficiency: Efficiency = Work output / Heat input. First, let's determine how much heat is not passed on to the lower temperature reservoir: 425 - 295 = 130 J. Thus, the work done by the system is the heat that is not passed on, which is 130 joules.
-70 Joules
work is -25 joules

A certain system absorbs 350joules of heart and has 230joules of work done on it. What is the value of Delta?
400 joules.
The efficiency of the car's engine is calculated as the ratio of the useful work output to the total heat input. In this case, the useful work output is 500000 joules (2000000 J - 1500000 J) and the total heat input is 2000000 joules. Therefore, the efficiency is 500000 joules / 2000000 joules, which equals 0.25 or 25%.
The thermal energy change of the system can be calculated using the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. Therefore, the thermal energy change would be 100 J (heat added) - 60 J (work done) = 40 J.
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.
