The first law of thermodynamics provides the definition of the internal energy of a thermodynamic system, and expresses its change for a closed system in terms of work and heat. A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. In thermodynamics, a quasi-static process (also known as a quasi-equilibrium process; from the Latin quasi, meaning as if), is a thermodynamic process that happens slowly enough for the system to remain in internal physical (but not necessarily chemical) thermodynamic equilibrium.An example of this is quasi-static expansion of a mixture of hydrogen and oxygen gas, where the A heat source generates thermal energy that brings the working substance to the higher temperature state.
