... a) A simple engine uses a perfect gas as the working fluid in a piston-cylinder system. The gas is first heated at constant pressure from state 1 to state 2, then cooled at constant volume to state 3 where T3=T1, and then cooled at constant temperature, thereby returning to state 1.

Insulated glazing
Insulated glazing (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane) is double or triple glass window panes separated by a vacuum or other gas filled space to reduce heat transfer across a part of the building envelope.Insulated glass units are manufactured with glass in range of thickness from 3 mm to 10 mm (1/8"" to 3/8"") or more in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are manufactured with the same thickness of glass used on both panes but special applications such as acoustic attenuation or security may require wide ranges of thicknesses to be incorporated in the same unit.
