#### Definitions

Who demonstrated experimentally that there is a direct relationship between volume and pressure of a gas? Boyle
What is the name of the law that describes that there is a direct relationship between volume and temperature of a gas? Charles
What is the name of the law that combines Boyle's Law and Charles' Law to account for two independent variables? The Combined Gas Law
What is the ideal gas law? PV=nRT
What is the formula for density? mass/volume
What is the volume of 1 mol of a gas at STP? 22.4 L
What temperature unit is used when solving Charles' Law equations? Kelvin (K)
What is the unit most commonly used for density of a gas? g/L
When using atm, L, K, and mol, what is the value of the ideal gas constant? 0.0821
What letter represents the ideal gas constant? R
Whose law states that: "When measured at the same temperature and pressure, the ratios of the volumes of reacting gases are small whole numbers? Gay-Lussac's Law
What is the formula for the Combined Gas Law? P1V1/T1 = P2V2/T2
If you are given the volume of a gas in L, how do you convert that to moles? Divide by 22.4
If the pressure of a gas is increased, what will happen to its volume? It will decrease
Identify what P, V, n, and T stand for in the equation PV=nRT P is pressure, V is volume, n is number of moles, and T is temperature
