Hyperbaric Study Questions with correct answers

Pressure is defined as CORRECT ANSWER-The force per unit area acting on a surface in a direction perpendicular to that surface Gas is defined as CORRECT ANSWER-A phase of matter In the gas phase, the atoms or molecules basically move CORRECT ANSWER-Randomly Liquids change to a gas at CORRECT ANSWER-their respective boiling points Hydraulics is a branch of science and engineering concerned with the mechanical properties of CORRECT ANSWER-Liquids When applying pressure to a fluid, the pressure is exerted CORRECT ANSWER-In all directions equally A mechanical gauge is used when measuring gas pressure in a sealed container. For all common pressure gauges, the pressure indicated on the gauge is CORRECT ANSWER-Less than absolute pressure because gauges (and gauge pressures) ignore the ambient (barometric) pressure around us. They ony measure the extra pressure in the container. Absolute pressure can be defined as CORRECT ANSWER-The amount of pressure within the sealed vessel + the amount of pressure outside the sealed vessel
