In thermodynamics, work done by a system on its surroundings or another system is said to be positive.
work done by the system increases entropy of the surroundings
work is said to be positive when both the force and displacement is acting on the same direction
Entropy
Reversible adiabatic expansion/compression
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
1. You'd have to add heat at precisely the same rate that the gas is doing work.

yes the word "thermodynamic" can be called a sentence. "THERMO" means heat and "DYNAMICS means motion or movement. -Thermodynamic refers to the study of heat and temperature and their relation to energy and work.

The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.
Enthalpy is a thermodynamic property of a thermodynamic system.
when work is positive and when playing is negative
Thermodynamic cycle is based on 2nd law of thermodynamics.
Yes, internal energy is a thermodynamic function or state function,
No, this will not work. Postitive to Negative/Negative to Positive will work.
