Hi there!
The first law of thermodynamics gives the relationship between heat absorbed and work performed. It does not restrict on the direction of heat flow. However, the flow of heat is unidirectional from higher temperature to lower temperature.
All naturally occurring processes will tend to proceed on their own in only one direction. A gas expands by its own to fill the available volume of the container in which it is kept.
Mixing of two gases is a spontaneous process.
The gas in a container will not spontaneously contract in one corner.
A spontaneous process is an Irreversible process and may only reversed by some external agency. Exothermic reactions may be taken spontaneous. Evaporation of water is endothermic. Though water absorbs heat, the vapourisation is spontaneous.
This is because entropy change is positive.
In an isolated system there is always a tendency for the system to become more disordered or chaotic. This could be a criteria for spontaneity of a physical or chemical change.
Gibbs energy change, ∆G = ∆H - T∆S, is one of the most important equation, as changes in enthalpy and entropy are present. ∆G gives the criteria for spontaneity at constant pressure and temperature.
Hope it helps!
