What else can I help you with?
Can work done on a system decrease its thermal energy?
Yes. As an example: if you define a refrigerator as your system, the work done on the system causes heat to be expelled from the system to the surroundings. The net heat expelled will be equal to the work input plus the decrease in its thermal energy.
When a system is doing work what happens to its temperature?
When a system is doing work, it can either increase or decrease in temperature depending on the type of work being done. If work is done on the system, its temperature may increase due to the input of energy. Conversely, if the system is doing work on its surroundings, it may lose energy and decrease in temperature.
What is the first law of thermodynamics applied to closed and open system showing the meaning of the positive and negative sign of heat and work?
The first law of thermodynamics 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. For a closed system, heat added to the system is positive if it is absorbed by the system, and negative if it is released by the system. Work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system. For an open system, the same principles apply but heat and work may also account for changes in the system's mass flow.
If work is don adiabatically on a system will the internal energy increase or decrease?
If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.
When is work done positive?
There are two conventions. One says that work done on the system is positive, the other says that work done by the system is positive. Chemists tend to use the former, physicists tend to use the latter... one of several reasons it's not a good idea to take thermodynamics in chemistry and physics at the same time.
Can work done on a system decrease its thermal energy?
Yes. As an example: if you define a refrigerator as your system, the work done on the system causes heat to be expelled from the system to the surroundings. The net heat expelled will be equal to the work input plus the decrease in its thermal energy.
What is the work done by the system according to the sign convention?
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.
Is the work done by the system is considered as positive or on the system is considered as positive?
In thermodynamics, work done by the system is considered positive. Work done on the system is considered negative.
Work done on the system is?
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
What is the relationship between the work done on the system and the work done by the system in a thermodynamic process?
In a thermodynamic process, the work done on the system is equal and opposite to the work done by the system. This is based on the principle of conservation of energy, where the total work done in a closed system remains constant.
What is the relationship between the work done on a system and the work done by a system in a thermodynamic process?
In a thermodynamic process, the work done on a system is equal and opposite to the work done by the system. This is known as the principle of conservation of energy.
Expansion happens because?
there is too much pressure in a system. example, a system which has done work and releases heat will expand itself
How do you determine a work done is positive sign or negative sign?
If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
Does the work done on a system necessarily change the system's kinetic energy?
Yes, the work done on a system can change the system's kinetic energy.
Is the work done on a system positive or negative?
The work done on a system is positive when energy is added to the system, and negative when energy is removed from the system.
How can you find the initial velocity form the work done on a system?
To find the initial velocity from the work done on a system, you can use the work-energy principle. The work done on the system is equal to the change in kinetic energy of the system. By equating the work done to the change in kinetic energy and solving for the initial velocity, you can find the initial velocity of the system.
What is the relationship between the work done by the system and the win?
The relationship between the work done by the system and the win is that the work done by the system contributes to achieving the win. The effort and performance of the system directly impact the outcome or success of the win.
