If you increase the temperature of a gas trapped in a non-flexible container, the pressure will...
stay the same
increase
decrease
cause diffusion
In an "inverse relationship", such as Boyle's Law, when one variable shows an increase the other variable...
increases as well
remains constant
shows a flat line on a graph
decreases
According to Charles's Law, if the temperature of a gas decreases then the volume of that gas ...
decreases
increases
remains constant
is shown on a graph with a curved line
When diffusion takes place, it occurs along a concentration gradient from ...
smallest molecular mass to largest molecular mass
least concentrated to most concentrated
most concentrated to least concentrated
largest molecular mass to smallest molecular mass
If you increase the number of moles (or particles) of a gas trapped in a rigid container, the pressure ...
remains constant, only kinetic energy of molecules increases
decreases as this is an inverse relationship
increases as this is a direct relationship
would be expressed with a flat line on a graph
If the volume of a gas increases then the pressure of that gas ...
decreases
increases
remains constant
is shown on a graph as a linear relationship
The Combined Gas Law allows you to analyze a change in which conditions for a gas?
the temperature and pressure
the pressure and volume
the pressure and volume and temperature
the number of moles (molecules) present
When two gases of unequal mass, say CO2 and O2, come to equilibrium at a constant temperature ...
they cease their random motion and separate by molecular mass
they lose their kinetic energy and slow down
they maintain random motion
they increase their kinetic energy due to molecular collisions
If you blow up a balloon and then place it in the freezer, according to Charles's Law it will
explode
get smaller
get larger
freeze
A graph of a gas law that shows a direct relationship will have...
a line that looks like a hyperbola
a flat line across the center of the graph
a line that shows a straight-line relationship
a line that starts out flat and then rises to show a straight-line relationship
When solving Gas Law problems, you have to remember to...
convert K to oC
convert mL to L and oC to K
ignore unit differences and multiply values
convert atm to kPa or mmHg
A graph of a Gas Law that shows an inverse relationship will show...
a flat line in the middle of the graph
a straight-line relationship from the origin
an exponential growth curve
a hyperbola
Which manometer shows that atmospheric pressure is greater than the pressure of a trapped gas?
the first manometer on the left
the second manometer in the middle
the third manometer on the right
both the second and third manometers
This type of instrument can be used to determine whether a storm is coming into an area. What is the instrument called?
a manometer
a weather vacuum
a mercury pressure gauge
a barometer
Which of the following is a correct equality for which you could write a conversion factor to solve a gas law problem?
1 atm + 101.3 kPa = 760 mm Hg
1 atm = 101.3 mm Hg
101.3 kPa = 760 torr
1 torr = 1 atm
