    Low-pressure area - Wikipedia

    In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere.The formation process of a low-pressure area is known as cyclogenesis.Within the field of meteorology, atmospheric divergence aloft occurs in two areas.

    Steam engine - Wikipedia

    A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.The term "steam engine" is generally applied only to reciprocating engines as just

    Air conditioning (often referred to as AC, A/C, or air con) is the process of removing heat and controlling the humidity of the air in a space. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals; however, air conditioning is also used to cool and

    A steam steriliser, also known as an ‘autoclave’, uses saturated steam at 121–132 °C. A typical standard for steam sterilisation is achieved after 15 to 30 minutes under a pressure of 106 kPa (1 atm) once all surfaces have reached a temperature of 121 °C (Block, 2000). To insure reliability of this sterilisation method, the critical
