In thermodynamics, positive work is done on a system when energy is transferred from an external source to the system, resulting in an increase in the system's energy. Negative work, on the other hand, is done by a system when energy is transferred from the system to an external source,...
are, moreover,heatand work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature. Hence, heat transferred may become thermal energy, while work done maymanifestitself in the form ofmechanical ...
In physics, the term work refers to the transference of energy that occurs when a force is applied to a body that is moving in such a way that the force has a component in the direction of the body's motion. Thus work is done on a weight that is being lifted, or on a spring tha...
In other words, the system does work on the surroundings, or positive work is done by the system rather than on the system. If a gas compresses, things are the other way around. In thermodynamics, one adopts a definition of "work" and specifies whether it is positive...
work done will be zero. Lets more simplify the definition of work with an example, suppose a box is placed at the position “p” and when we push the box in forwarding direction, that means we are applying force to the box and the box moved to the new position “q” that means its...
whenever work is done, energy is transferred. for a work to be done, in a scientific sense, a force must be exerted, and there must be displacement in the direction of the force. with this said, we can say that work is the product of the component of the force in the direction...
How to Calculate the Work Done by a Heat Engine Step 1: Determine how much heat is taken in by the engine. Step 2: Determine how much heat is exhausted into the surroundings. Step 3: Subtract the answer to step 2 from the answer to step 1 to determine the work done by the engi...

How can the formula for power (power = work done/time taken) be explained? According to the first law of thermodynamics, if the internal energy is equal to the change in heat added to the system and the work done by the system, then what would be the change in energy of the system ...
