When is work done negative and when work done is positive in thermodyn

1.	When is work done negative and when work done is positive in thermodynics?
Answer» The first law is simply a conservation of energy equation: The INTERNAL energy has the symbol U. Q is POSITIVE if heat is ADDED to the system, and negative if heat is REMOVED; W is positive if workis done by the system, and negative ifwork is done on the system.
