The Ideal Gas Law
Describe the properties of an ideal gas.
- The classical model of an ideal gas assumes that the instantaneous velocities of atoms are random, the volumes of the atoms are negligible compared to the total volume occupied by the gas, the atoms collide elastically, and the only appreciable forces on the atoms are those that occur during collisions.
- An ideal gas is one in which the relationships between pressure, volume, the number of moles or number of atoms, and temperature of a gas can be modeled using the equation:
- Graphs modeling the pressure, temperature, and volume of gases can be used to describe or determine properties of that gas.
- A temperature at which an ideal gas has zero pressure can be extrapolated from a graph of pressure as a function of temperature.
