​in which P is Absolut pressure (Instead of gauge pressure), V is the volumen of the gas, n is the amount of particles measured in moles, T is absolut temperature (measured in Kelvin), and R is just a constant with a value of 8.314J/mol*K.

​Thermodynamic process

• ​A thermodynamic process is defined as a change from one equilibrium macrostate to another macrostate.

​Types of Processes:

​Isochoric (Isocóricos, Isovolumetricos o Isométricos in spanish):

​Volume is constant. (V=cte)

​Isobaric (Isobáricos) The Pressure remains constant. (P=cte)

​Isothermic : Temperature remains constant. (T=cte)

​Adiabatic: There is no heat entering or leaving the system. (Q=0)

​ISOCHORIC (V=cte)

​Isobaric Process (P=cte)

​Isothermic (T=Cte)

​A line in the PV graph in which the temperature Is constant is called an Isothermal

​Adiabatic (Q=0)

​Thermodynamic cycle

​A thermodynamic cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventually returns the system to its initial state.
