?1 List all 5 parts of the Kinetic Molecular Theory.
Answer 1) Gases consist of large numbers of tiny particles that are far apart relative to their size. 2) Collisions are elastic. 3) Gas particles are in continuous, rapid, random motion. 4) There are no forces of attraction or repulsion between gas particles. 5) The average kinetic energy depends on temperature of the gas.
?2 A spontaneous mixing of two gases caused by random motion is _____________.
Answer Diffusion
?3 Give an example of diffusion
?4 _________ is a process by which gas particles pass through a tiny opening.
?5 Give an example of effusion

?7 What is standard temperature in Celsius and Kelvin?
?8 What is standard pressure in atm?
?9 Convert -10.0°C to K.
?10 Convert 125mmHg to atm
?11 According to the KMT, what will happen when two gas particles collide?
They will have an elastic collision and their energy will be conserved (no loss or gain of energy).
?12 Draw the 3 graphs relating temperature, pressure, and volume.
