Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as Negative
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.
When do you say that the work done is positive or negative?
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
What is the significance of the work done on the system in relation to the sign convention?
The significance of the work done on the system in relation to the sign convention is that it helps determine whether work is being done on the system (positive work) or by the system (negative work). This understanding is crucial in analyzing the energy transfer within the system and its surroundings.
Is the work done on a system negative in the given scenario?
In the given scenario, if the force applied to the system is opposite to the direction of the displacement, then the work done on the system is negative.
Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as Negative
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.
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.

When swimming work done is positive or negative?
Positive.
Why work done on the system is negativeand it is positive when its done by the system?
Oh, dude, it's like this: when work is done on the system, it's like the system is just chilling and getting stuff done to it, so it's negative because it's like, "Ugh, why are you messing with me?" But when the system does work, it's like, "Yeah, I got this," so it's positive because it's like, "I'm in control, baby!" So, yeah, that's why it's negative when done on the system and positive when done by the system.

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 internal energy of a system is a function of its state. Any increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system." In equations, this is stated as: DU = DQ + DW where DU is the INCREASE in internal energy DQ is the heat SUPPLIED DW is the work done ON the system So, if heat is lost by the system, it means that DQ is negative and if work is done by the system, it means that DW is negative. The best way to answer thermodynamics questions involving the first law is to think logically about what calculations should be made. If you do this, you will never make mistakes about signs.
Is the work done on a system negative in the given scenario?
In the given scenario, if the force applied to the system is opposite to the direction of the displacement, then the work done on the system is negative.
Can work done be negative in a physical system?
Yes, work done can be negative in a physical system when the force applied is in the opposite direction of the displacement.
Is the work done by friction always negative?
No, the work done by friction can be either positive or negative, depending on the direction of the force and the displacement of the object.
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..........
