Pascal


What is another unit of pressure that is equal to 10 to the 5th power of pascals?

Bar


What is the typical pressure at sea level that is 760mm Hg high (1atm) ?

Standard Atmospheric Pressure


What is 760mm Hg equal to?

1atm


The volume of a fixed quantity of gas maintained at constant temperature is inversely proportional to the pressure.

Boyle's Law


The volume of a fixed amount of gas maintained at constant pressure is directly proportional to its absolute value.

Charles's Law


Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.

Avogadro's Hypothesis


The volume of a gas maintained at a constant temperature and pressure is directly proportional to the number of moles of the gas.

Avogadro's Law


PV = nRT

Ideal  Gas Equation


What is a hypothetical gas whose pressure, volume, and temperature behavior is completely described by the ideal  gas equation.

Ideal Gas


What is R in the ideal  gas equation?

The gas constant.


What are the conditions 0 degrees Celsius and 1 atm referred to as?

Standard Temperature and Pressure


What is the pressure exerted by a particular component of a mixture of gases?

Partial Pressure


What is Dalton' observation that the total pressure of a mixture of gases equals the sum of the pressures that each would exert if it were present alone referred to as?

Dalton's Law of Partial Pressures


What is the dimensionless number that expresses the ratio of the number of moles of one component to the total number of moles in the mixture referred to as in the equation PV = nRT?

n


What is the explanation of pressure and temperature at the molecular level referred to as?

Kinetic  Molecular Theory


What is the value of the speed, u, of molecules expressed as?

What is the escape of gas molecules through a tiny hole into an evacuated space called?

Effusion


What is the spread of one substance throughout a space or a second substance called?

Diffusion


The fact that the effusion rate of a gas is inversely proportional to the square root of its molar mass.
