Section 5.1

Know the basic units of pressure.
The basic units of pressure are atmospheres, psi, mm of Hg, torrs, and Pascals (Newtons per square meter)

Know the difference between gage and atmospheric pressure.
Atmospheric pressure is the pressure exerted by the earth's atmosphere at any given point, being the product of the mass of the atmospheric column of the unit area above the given point and of the gravitational acceleration at the given point. Gage pressure is measured on a pressure gage and is above or below atmospheric pressure.

Section 5.2

Know Boyle’s Law and its assumptions.
Boyle’s Law is a principle which says for relatively low pressures, the pressure of an ideal gas kept at constant temperature varies inversely with the volume of the gas. It describes the inversely proportional relationship between the absolute pressure and volume of a gas, if temperature if kept at a constant.

Know Charles’s Law and its assumptions.
Charles’s Law (also known as the law of volumes) is an experimental gas law which describes how gases tend to expand when heated. At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale. It can be written as V∞T where V is the volume or the gas and T is the absolute temperature.

Know Gay Lussac’s Law and its assumptions.
Gay Lussac’s Law is concerned with the properties of gases. It is the principle that, for relatively low pressures, the density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas.

Know Avogadro’s Law and all its assumptions.
Avogadro’s Law is the principle that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. Thus, the molar volume of all ideal gases at 0° C and a pressure of 1 atm. is 22.4 liters.

What is the I.G.L. and where does it come from?
The I.G.L. is the equation...
