Question

greater work is? a)+100j b)-100j c)-1000 j d)+200​

Answer 1

Answer:

which one of the following is a greater work

a,+100, b-100, -1000, d+200

Answer 2

Concept :

According to thermodynamics, a system performs work when it transfers energy to its surroundings by a mechanism that allows the system to voluntarily exert enormous forces on those surroundings. Work applied to the system denotes that something other than the heat effect known did something to improve the system's internal energy. The underlying system energy diminished as a result of its effort on anything external to the system. The system's work, or the work that the gas does, is positive. Consider the expansion of gas during heating. The system is being worked on negatively. An illustration would be a constant force acting on a cylinder's piston.

Given: a multiple-choice question about work done.

Find, the greater work done

Solution:

According to the problem,

the given four options are $+100j , -100j ,-1000 j ,+200j$

maximum work done by a system = $+ 200 J$

If maximum work done on a system =  $- 1000J$

Hence maximum work done by a system is $+200j$, maximum work done on a system is $-1000j$
