What is Isothermal Work?

Isothermal work is the energy transferred to or from an object via the application of force along with a displacement for a system whose temperature is constant. Given the value of volume at point 1 and the respective pressures, the isothermal work can be calculated. Positive work adds energy to a system. Negative work removes or dissipates energy from the system.
