Chapter 13 and 14 Review Make sure you come prepared with your foldables and a calculator.
The change of a solid directly to a vapor. • Evaporation • Sublimation • Condensation • Solidification
All matter consists of tiny particles that are in constant motion. • Particle theory • Constant motion theory • Kinetic theory • Movement theory
The pressure resulting from the collision of atoms and molecules with objects • Atomic pressure • Molecular pressure • Collision pressure • Atmospheric pressure
The energy an object has due to its movement • Active energy • Kinetic energy • Potential energy • Movement energy
A device that measures the atmospheric pressure • Barometer • Atmometer • Pressure reader • Atmospheric recorder
PV = nRT • Boyle’s Law • Charles’s Law • Combined Law • Ideal Gas Law
For a given mass of a gas at constant temperature, the volume of the gas varies inversely with pressure (P1V1=P2V2) • Boyle’s Law • Charles’s Law • Gay-Lussac’s Law • Combined gas Law
The total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases. • Graham’s Law of effusion • Combined Gas Law • Dalton’s Law of Partial Pressure • Gay-Lussac’s Law
The escape of gas through a small hole in the container. • Diffusion • Escapism • Porision • Effusion
A measure of how much the volume of matter decreases under pressure. • Shrinkibility • Compressibility • Pressurization • Volumization
SI unit of pressure Pascal (Pa)
What unit of temperature is used to calculate the gas laws? Kelvin (K)
The volume of a gas is .25 L at 340.0 kPa pressure. What will the volume be when the pressure is reduced to 50.0 kPa? 1.7 L
A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0 degrees C. What will the volume of the balloon be if the temperature is increased to 80.0 degrees C?(Pressure is constant) 36.8 L
A rigid container of oxygen gas has a pressure of 340 kPa at a temperature of 713 K. What is the pressure at 273 K? 130 kPa
A gas occupies a volume of .14 L at 35.0 degrees C and 97 kPa. What is the volume at 0 degrees C and 101.3 kPa? T1 = 35.0 + 273 = 308 K P1 = 97 kPa T2 = 0 + 273 = 273 K P2 = 101.3 kPa V1 = .14 L Since you have all three variables you use the combined gas law: V2 = (P1 x V1 x T2)/(T1 x P2) = .12 L
The gaseous product of a reaction is collected in a 25 L container at 27 degrees C. The pressure in the container is 300.0 kPa and the gas has a mass of 96.0 g. How many moles of the gas are in the container? V = 25 L T = 27 + 273 = 300 K P = 300 kPa R = 8.31 n = ? Grams are not a part of the equation so ignore them. They were added as a distraction. PV=nRT n = (PV)/(RT) = (300 x 25)/(8.31 x 300) = 3 mol
