Volume
Temperature
30s - Q2
Which of these is NOT correct under Kinetic Molecular theory?
Gas molecules are constantly moving.
There are attractive intermolecular forces, such as London dispersion forces,
between gas molecules.
The volume of the gas molecules themselves is negligible compared with the
volume of the container.
The pressure is related to the number of collisions the molecules make with the walls of the container.
30s - Q3
Which of the following illustrates mathematical statement for Charles’ Law?
V1 / n1 = V2 / n2
V1 / T1 = V2 / T2
P1V1 = P2V2
P1 / T1 = P2 / T2
30s - Q4
Why does the air pressure inside the tires of a car increase when the car is driven?
The atmosphere compresses the tire.
The air particles inside the tire increase their speed because their temperature rises.
Some of the air has leaked out.
The air particles collide with the tire after the car is in motion.
30s - Q5
What does the constant bombardment of gas molecules against the inside walls of a container produce?
Density
Pressure
Temperature
Force
30s - Q6
Which temperature represents absolute zero?
273.15°C
273.15 K
0°C
0 K
30s - Q7
Suppose the temperature of the air in a balloon is increased. If the pressure remains constant, what quantity must change?
Compressibility
Adhesion
Volume
Number of molecules
30s - Q8
A sample of argon gas at standard pressure occupies 1000 mL. At constant temperature, what volume does the gas occupy if the pressure increases to 800 mm Hg?
(standard pressure = 760 mm Hg)
1053 mL
500 mL
760 mL
950 mL
60s - Q9
What happens to the lungs of a scuba diver as it moves closer to the seafloor?
The lungs compress
There is no change in the lungs.
The lungs expand.
The lungs explode
60s - Q10
A 180.0 mL volume of gas is measured at 87.0°C. If the pressure remains unchanged, what is the volume of the gas at standard temperature of 273 K?
410 mL
137.0 mL
565 mL
0.5 mL

30s - Q12
Which is true about disaccharides?
They are formed when two amino acids are formed together.
They are formed when two nucleotides are formed together.
They are isomers of polysaccharides.
They are polymers of monosaccharides.
