Re: Work
Work is done on a system if its value is positive; this is because the system absorbs energy from its surroundings.
The opposite should in turn make sense: if the system is doing work, its value is negative because energy is leaving the system to go to the surroundings.

Re: Work
The work done on a system is always positive since energy is spent on the system and the system gains the energy spent whereas the work done by the system is negative since the system spends energy and it is lost to its surroundings which gain this energy.

Re: Work
So if it's losing energy to the surroundings, work is negative, while if the system is gaining energy, it is positive.

Re: Work
If a system is losing energy to the surroundings, then work is negative, and if it is gaining energy from the surroundings, then work is positive.
