Q#5. Choose the correct answer: RED arrow represents heavier gas.
Q#6. Ideally, the collisions of gas molecules can be thought as ____________
_______________ _________________ which, in physics, means there is no loss of Kinetic
Energy or momentum.
Q#7. What is the relationship between the mass of a gas molecule and its velocity?
Q#8. Ideally, we can think of different sized molecules of gas as taking up __________
volume. In other words, different sized molecules are mathematically equivalent points in
space.
Q#9. A student sets up an experiment to compare the deflation rate of
different gases. The student chooses helium and argon and inflates two
identical balloons to the same pressure, volume, and temperature. Over
time, the student notices that the helium balloon deflates faster than the
argon balloon. Why?

would be ____________________________________ , compared to the same element in a
gas phase.
