Hello,
I'm reading a book about a gas volume inside a system. It says that when the volume expands due to the heated gas, the system is doing work. I understand that part. But it says that the value for work is negative because the system is doing work.
From all the physics I have been studying over the years, work is positive when the system does work and negative when the surroundings do work on the system. Isn't this right?
Thanks
