Charles’ Law states:
gases are compressible
an increase in pressure is a direct result of an increase in temperature
an increase in volume is caused from an increase in pressure
an increase in volume is a direct result of an increase in temperature
an increase in volume will cause a decrease in pressure

Which of the following statements is inconsistent with assumptions made by the kinetic molecular theory of gases?
Gas molecules repel and attract other gas molecules
Gas particles are in constant motion
An increase in temperature causes an increase in the speed of the gas particles
There is a lot of space between the particles compared to their size
Collisions are elastic. When two particles collide they bounce back like billard ball collisions
Which of the following statements most correctly describes the relationship between vapor pressure and boiling point of a volatile liquid?
a liquid with a low vapor pressure is volatile so it has a low boiling point
a liquid with a high vapor pressure has a high boiling point
a liquid with a high vapor pressure is volatile so it has a high boiling point
all the above represent a non-volatile liquid
a liquid with a high vapor pressure has a low boiling point
