Gas Packet Questions updated 2026
Answer :A gas atom or molecule. - Quiz :In Model 1, what does a dot
represent?
Answer :Glass and metal are nonflexible. - Quiz :Name two materials that the
containers in Model 1 could be made from that would ensure that they were
"nonflexible?"
Answer :Temperature is related to average kinetic energy, and thus to the
length of the arrows. - Quiz :In Model 1, the length of the arrows represents
the average kinetic energy of the molecules in that sample. Which gas variable
(Pinternal, V, T or n) is most closely related to the length of the arrows in
Model 1?
Answer :Controlling the volume requires a nonflexible container because any
time the internal pressure is dif- ferent from the external pressure the
container would expand or contract if it were flexible. You need a nonflexible
container to contain a gas with an internal pressure that differs from the
external pressure. - Quiz :Of the variables that were controlled in both
Experiment A and Experiment B in Model 1, one requires a nonflexible
container. Name this variable, and explain why a nonflexible container is
necessary. In your answer, consider the external and internal pressure data
given in Model 1.
Answer :How hard the molecules hit and how often they hit the sides of the
container. - Quiz :Read This!
Pressure is caused by molecules hitting the sides of a container or other
objects. The pressure changes when the molecules change how often or how
hard they hit. A nonflexible container is needed if the gas sample is going to
have an internal pressure that is different from the external pressure. If a
, flexible con- tainer is used, the internal pressure and external pressure will
always be the same because they are both pushing on the sides of the
container equally. If either the internal or external pressure changes, the flex-
ible container walls will adjust in size until the pressures are equal again.
Name the two factors related to molecular movement that influence the
pressure of a gas.
Answer :As more molecules are added to a flask, they hit the sides of the flask
more often and increase the pressure. - Quiz :Provide a molecular-level
explanation for the increase in pressure observed among the flasks of
Experiment A.
Answer :As the gas molecules are heated, their average kinetic energy
increases. They hit the sides of the container more often and also harder,
which increases the pressure. - Quiz :Provide a molecular-level explanation for
the increase in pressure observed among the flasks of Experiment B.
Answer :As more gas molecules were added, the internal pressure would
increase at first. That would push the sides of the flexible container outward,
causing the volume to expand until the pressure equalized. - Quiz :Predict
what would happen to the volume and internal pressure in Experiment A of
Model 1 if a flexible container were used.
Answer :As the gas molecules are heated, the internal pressure would
increase at first. That would push the sides of the flexible container outward,
