1. What are the components of Kinetic Molecular Theory?
a. ____All Gases are Matter (have mass and take up
space)_______________________
b. ____These particles are in constant, rapid and random
motion._________________
c. ___All collisions are perfectly elastic. (no energy is lost
in the collision)__________
d. __The force of gas particle collisions on the walls of the
container creates pressure; however, gas particles do not
exert force on each other._____________________
e. ___At a given temperature, all gas particles have the
same amount of kinetic energy (temperature).__
f. ___The distance between gas particles is very
large._________________

temperature was 25.0 °C, what would the final temperature
of the gas be?
11.A container holds three gases: oxygen, carbon dioxide, and
helium. The partial pressures of the three gases are 2.00
atm, 3.00 atm, and 4.00 atm, respectively. What is the total
pressure inside the container?
12.A gas has a volume of 800.0 mL at 23.00 °C and 300.0 torr.
