Document Summary
Pressure is defined as the force exerted per unit area of surface. Pascal (pa) is the si unit of pressure. A barometer is a device for measuring the pressure of the atmosphere. Manometer is a device that measures the pressure of a gas or liquid in a sealed vessel. Millimeters of mercury (mmhg) is a unit of pressure also known as the torr. The atmosphere (atm) is a related unit of pressure equal to exactly 760 mmhg. Boyle"s law is the volume of a sample of gas at a given temperature varies inversely with the applied pressure. (p1v1 = p2v2) Charles"s law is the volume occupied by any sample of gas at a constant pressure is directly proportional to the absolute temperature. Combined gas law: relating volume, temperature, and pressure. Avogadro"s law: equal volumes of any two gases at the same temperature and pressure contain the same number of molecules. Molar gas volume: the volume of one mole of gas.
