Lowest kinetic energy, no compression

What are the properties of a liquid?

Some kinetic energy, slight compression

Most kinetic energy, compressible

An ideal gas is one that:

0 °C (273.15 K) and 1 atm (760 torr)

What is Dalton's Law of Partial Pressure?

The total pressure exerted by all gases in a sample is equal to the sum of the pressures of all the gases

·         P_total = P₁ + P₂ + P₃ + ….

The mole fraction of an individual gas is

The number of moles of that gas divided by the total moles of gas present

X1=n1/ntotal

What is the Kinetic-Molecular Theory?

The model that explains gas behavior in terms of particles in random motion whose volumes and interactions are negligible

-a gas consists of a large collection of individual particles

-   the particles are very small in volume compared to the volume of the container

-     the individual particles are in constant, random, straight-line motion

- The straight-line motion is changed after impact with other particles or the walls of the container

 - collisions are elastic

- energy is transferred to the object the particle collides with but not through friction so kinetic energy remains constant

If two gases have the same kinetic energy (E_k) and

E_k = ½ (mass)(speed²)

then the gas with greater mass must be moving at a ______ speed.

An ideal gas is one that exhibits a linear relationship between:
