Unit 9 Gas Laws Test

P1V1 = P2V2

In a gas, pressure and volu8me are inversely related when temperature is held constant

V1/T1 = V2/T2

Volume(L or mL) and temperature (K) have a direct relationship at constant pressure

P1/T1 = P2/T2

Pressure and Temperature are directly related when volume is held constant

States the relationship between pressure, volume, and temperature of a fixed amount of gas

P1V1/T1 = P2V2/T2

measure of the force of a collision in a given area

measurement scientist use to determine the amount of space matter takes up

the amount of volume or space that a mole of any gas at STP (0 degrees celsius and latm) would occupy

1 atm = 760 mmHg = 101kPa

1 dm3 = 1L = 1000mL = 1000cm^3

1 mol = 22.4

the average kinetic energy or movement of particles

K = C + 273

the physical behavior of an ideal gas in terms of the pressure, volume, temperature, and number of moles of a gas present

PV = nRT

8.314 (kPa)(L) / (mol)(K) = 62.36 (mmHg)(L) / (mol)(K) = 0.00821 (atm)(L) / (mol)(K)

The total pressure of a mixture of gases is the sum of the partial pressures of the individual gases

Ptotal = P1 + P2 + P3 ….

The rate of effusion (or diffusion) of a gas is inversely related to its molar mass

gas molecules spread from high concentration to low concentration.

gas molecules ability to pass through a small opening.

faster

Rate of effusion for gas 1/Rate of effusion for gas 2 = √MW2/√MW1
