Question | Answer |
---|---|
Pressure | the amount of force exerted per unit area of a surface |
Newton | The SI unit for force,the force that will increase the speed of a 1kg |
Barometer | an instrument that measures atmosphere pressure |
Milimeters of Mercury | a unit of pressure |
Atmosphere of pressure | the pressure of earth atmosphere at sea level exactly equivalent to 760 mm Hg |
Pascal | The SI unit of pressure equal to the force of 1 N exert over an area of 1 m2 |
Partail Pressure | the pressure of each gas in a mixture |
Daltons law of partial pressure | The law that states that the total pressure of a mixture of gases is equal to the sun of the partial pressure of the component gases |
Boyles law | The law that states that for a fixed amount of gas at a constant temperature ,the volume of the gas increases as the pressure of the gas decreases and the volume of the gas decreases as the pressure of the gas increases |
Absolute zero | The temperature at which all molecular motion stops |
Charles law | The law that states that for a fixed amount of gas at a constant pressure the volume of the gas increases as the temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases |
Gay-lussacs law | The law that states that the volume occupied by a gas at a constant pressure id directly proportional to the absolute temperature |
combined gas law | the relationship between the pressure,volume,and temperature of a fixed amount of gas |
Avogados law | the law that states that equal volumes of gases at the same temperature and pressure contain equal number of molecules |
standard molar volume of a gas | The molar volume of a gas of one mole of a gas at STP |
ideal gas law | the law that states the mathematical relationship of pressure |
ideal gas constant | the proportionality constant that appears in the equation of state for 1 mole of an ideal gas |
Garhams law of effusion | The law that states that the rate of effusion of a gas is inversely proportional to the square root of the gas density |
