Hi dear, 

An adiabatic process or an isocaloric process is a thermodynamic process in which no heat is transfered to or from the working fluid. The term "Adiabatic" literally means impassable. Adiabatic boundary is a boundary that is impermeable to heat transfer and the system is said to be adiabatically insulated. 

dS = dQ / T

Where S is the entropy, Q is the energy (heat) and T is the teperatue.

The second law of thermodynamics state that entropy must either increase or stay  constant on every fenomena. If it stays  constant, it means that the process is reversible.

The law of conservation of energy is an empirical law of physics. It states that the total amount of energy in an isolated system remains constant over time (is said to be conserved over time). A consequence of this law is that energy cannot be created nor destroyed.

Hope this helps.
