Show:
Particles in motion...and other stuff...
This is a theory...and more...
Variables within the laws...and some not within the law...
Boyles Law..perhaps..
Charles Law..ok, maybe...
100
This is what happens when volume is increased and decreased with particles.
What are increase V= less collisions, decrease V = more collisions?
100
This is the name of the theory that explains particle movement.
What is the Kinetic Molecular Theory?
100
These are the 3 variables that affect the behavior of gases.
What are: temp, pressure and volume?
100
This is the variable held constant in Boyles Law, and the 2 variables used in the law calculation.
What are temperature=constant, pressure and volume used in calculations?
100
These are the 2 variables that are used when calculating Charles law and the one that stays constant.
What are temp and volume...and ...the one that is constant is pressure?
200
When temperature rises, this is what happens to the volume of a gas.
What is temperature rises = higher volume as particles spread out away from eachother?
200
These are the 4 parts of the main theory that explain particle motion.
What is the Kinetic Molecular Theory: 1. all atoms are composed of subatomic particles that when collisions occur loose no energy 2. at absolute zero, atoms are believed to stop moving 3. all matter made of atoms 4. particles of matter are always in constant motion
200
This is standard temperature, and standard pressure.
What is 0 degrees C=standard temp, standard pressure: 1 atm (unless given at 760mm)?
200
There is a sample of H gas with a volume of 200ml at 300.kPa. This is the pressure that gas would have in order to have a volume of 300.0mL. (show the work for points)
What is: P2 = V1 P1 / V2 = 200 x 300 / 300 = 200kPa?
200
This is the equation for Charles law.
What is V1/T1 = V2/T2?
300
This is the definition of pressure.
What is the result of particles colliding with their container..measurement of force per unit area..( More collisions = greater pressure.)?
300
This is a description of what would happen if a balloon were left in the sun for a few hours...be specific. (no change in pressure though)
What is as the balloon heats up, the volume of the air in the balloon increases. (pressure is constant)?
300
This is what happens to gas when the temperature decreases and the pressure remains constant.
What is its volume decreases?
300
This is the explanation of how volume and pressure are related at a constant temperature.
What is V Increase, P decrease...Boyles Law based on this principal?
300
Draw the graph of Charles law, label and state relationship with the variables in the graph.
What is a graph with a straight line: v=y, t=x and the relationship is directly proportional?
400
This is the explanation of why the pressure of gas enclosed in a rigid container changes when the gas is heated...be specific please.
What is when pressure increases due to TE increase, this = KE = equals more collisions?
400
If pressure is decreased from 600.mm to 400.mm Hg and the sample of He occupies 250.ml, this is the volume it occupies. (use G, F, S)
What is : G: V1 = 250.ml, P1=600.mm, P2=400.mm F: V2=P1 x V1 / P2 S: V2= 600. x 250. / 400 = 375mL
400
This is the new volume of a gas with an original volume of 90ml and a temp change from 60 degrees C to 0 degrees C. Use: G, F, S...
What is : G: V1 = 90ml, T1 = 333K, T2 = 273K F: V1/T1= V2/T2 S: 90/333=x/273 = 74ml
400
This is a draw that depicts a Boyles law graph with labels and relationship of variables.
What is the drawing with the curved line, p=y, v=x and the relationship is considered to be inversely proportional?
400
Using Charles formula solve: 200ml sample of He gas is gained at 300K, this is the volume of the He gas at 200K. Show G, F, S...
What is: G: V1=200, T1=300, T2=200 F: V1/T1 = V2/T2 S: 200/300 = x/200 = 133.33ml?
500
A jug of Hg occupies 20.L at a pressure of 200Kpa, this is the volume of the Hg when the pressure is increased to 520kPa. Use: G, F, S....(convert to mL for double points..)
What is : G: V1=20.0L, P1=200kPa, P2=520kPa F: V2=p1 (V1) / P2 S: V2 = 200 x 20. / 520 = 7.7L OR 7700ml (double pts)
500
This is the volume that a gas will occupy at 60 degrees C when the volume is 390ml and a temp of 72K is reached. Show: G, F, S.. (convert to L for double points)
What is : G: V1= 390ml, T1= 60+273 = 333K, T2=72K F: V1/T1 = x/T2 S: 390/333 = x/72 = 84.32ml OR .08432L

This is the reason why pressure of a sample of gas at a constant volume fall 75mm.
What is there is a temperature decrease?
500
200.ml is the volume of gas at a pressure of 1.atm, this is the pressure of this volume of gas at 2.0L. (Be careful.) Show: G, F and S...
What is: G= 200.ml (.2 L) = V1, 2.0L = V2, 1.atm = P1 Formula: P2=P1V1/V2 = Substitution: 1. (.2)/2.0 = .1 atm...?

In the belly of a fish there is 2.0ml of water at 6 degrees celcuis, this is the volume at 10 degrees C. Use : G, F, S..
What is : G: V1=2.0, T1 = 6+273=279, T2=283K F: V1/T1 = x/T2 S: 2.0/279 = x/283 = 2.03ml
