Adiabatic Pv Diagram


Adiabatic Pv Diagram - an adiabatic process occurs without transfer of heat or mass of substances between a thermodynamic system and its surroundings in an adiabatic process energy is transferred to the surroundings only as work the adiabatic process provides a rigorous conceptual basis for the theory used to expound the first law of thermodynamics and as such it is a key concept in thermodynamics a pressure volume diagram or pv diagram or volume pressure loop is used to describe corresponding changes in volume and pressure in a system they are monly used in thermodynamics cardiovascular physiology and respiratory physiology pv diagrams originally called indicator diagrams were developed in the 18th century as tools for understanding the efficiency of recall from the ideal gas law that pv nrt if n the amount of gas does not change then pv t we can use this relationship to determine how the temperatures at different.
