What is the value of internal energy in a cyclic process in thermodynamics?

∙ 7y ago
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.

What are variables for the first law of thermodynamics?
the internal energy (thermal energy)
Which law states that internal energy is function of Temperature?
The First Law of Thermodynamics states that the internal energy of a system is a function of temperature. It describes the relationship between heat transfer, work done, and changes in internal energy. It is a fundamental principle in the field of thermodynamics.
Which choice best explains what internal energy is as it relates to the first law of thermodynamics?
Internal energy is the sum of the kinetic and potential energies of the particles within a system. In the context of the first law of thermodynamics, internal energy represents the total energy of a system that can be exchanged with its surroundings through heat and work. The first law 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.
What happen to internal energy in non stable equilibrium state in engineering thermodynamics?
In a non-stable equilibrium state in engineering thermodynamics, the internal energy of the system is constantly changing as the system is not in a state of static equilibrium. Energy is being continuously exchanged with the surroundings, leading to fluctuations in internal energy. The system is not able to maintain a constant internal energy value as it is constantly responding to external influences.
Would nuclear fusion break the laws of thermodynamics?
No, nuclear fusion does not violate the laws of thermodynamics. It is a process that involves combining small atomic nuclei to form a heavier nucleus, releasing energy in the process. This energy release is consistent with the principles of thermodynamics.
What is PMM 1 why it is impossible?
WHAT IS PMM-1 A PMM1 is a Thermodynamic system that undergoes a cyclic process that produce no external affects other than the rise ( or fall) of a weight in a gravity field. WHY IS IT IMPOSSIBLE? PMM-1 state that work can still be produce in a cyclic process. This definition is against first law of thermodynamics and conservation of energy. According to first law of thermodynamics, in cyclic process E2- E1 = mg (h2 - h1) h2= h1 in cyclic process so the above equation yields E2=E1. where as according to PMM-1 you can produce work even when energy is zero (0), which makes it impossible

Is in the adiabatic process change in internal energy is equal to change in work done?
In an adiabatic process, where there is no heat exchange with the surroundings, the change in internal energy is equal to the negative of the work done. This relationship is a result of 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.
Which law states that internal energy is function of Temperature?
The First Law of Thermodynamics states that the internal energy of a system is a function of temperature. It describes the relationship between heat transfer, work done, and changes in internal energy. It is a fundamental principle in the field of thermodynamics.
What happened to Lost?
Well, thermodynamics is the science that studies this. According to the the first law of thermodynamics, all energy in all forms are conserved. The main types of energy we consider is kinetic, potential and internal energy. You may not be familar with Internal energy but it is another form of energy that we lump the energy of chemical bonds and kinetic and potential energies (ON THE MOLECULAR LEVEL) into it. Internal energy is proportional to the temperature of the object.
What does delta u stand for?
Delta "u" typically stands for change in internal energy in thermodynamics. It represents the difference between the final internal energy of a system and its initial internal energy. It is often used to calculate the heat and work interactions in a thermodynamic process.
Which choice best explains what internal energy is as it relates to the first law of thermodynamics?
Internal energy is the sum of the kinetic and potential energies of the particles within a system. In the context of the first law of thermodynamics, internal energy represents the total energy of a system that can be exchanged with its surroundings through heat and work. The first law 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.
What happens to internal energy when mechanical work is done?
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.
What happen to internal energy in non stable equilibrium state in engineering thermodynamics?
In a non-stable equilibrium state in engineering thermodynamics, the internal energy of the system is constantly changing as the system is not in a state of static equilibrium. Energy is being continuously exchanged with the surroundings, leading to fluctuations in internal energy. The system is not able to maintain a constant internal energy value as it is constantly responding to external influences.
What is internal energy of a substance?
Internal energy of a substance is the sum of the kinetic and potential energies of all the particles within the substance. It includes the energy associated with the motion and interaction of the particles. Internal energy is a crucial concept in thermodynamics and is used to describe the overall energy content of a system.
Would nuclear fusion break the laws of thermodynamics?
No, nuclear fusion does not violate the laws of thermodynamics. It is a process that involves combining small atomic nuclei to form a heavier nucleus, releasing energy in the process. This energy release is consistent with the principles of thermodynamics.
What is adiabatic expansion?
Adiabatic expansion is a process in thermodynamics where a gas expands without any heat being added or removed from the system, resulting in a change in pressure, volume, and temperature. This expansion typically occurs rapidly and can be described by the first law of thermodynamics, which states that the change in internal energy of a system is equal to the energy transferred to or from the system as work.
