1. Aim: What conditions would cause a gas to condense?
Essential Questions:
Why do real gases deviate from ideal gas laws under conditions of high pressure and low temperature?
“At extremely high pressures, gas volumes are higher than calculated.” Explain this research laboratory observation.
Relate attractive forces to boiling point.
How is vapor pressure of a substance related to temperature?
Why are pressure cookers a necessity for cooking foods at high altitudes?

Aim: What conditions would cause a gas to condense? Q: Why do real gases deviate from ideal gas laws under conditions of high pressure and low temperature?
Vocabulary: evaporation- the process by which particles escape from the surface of a non-boiling liquid and enter the gas state.
Condensation- the process by which a gas changes to a liquid.
H2o(g) H2o(l)
Vapor pressure- the pressure exerted by a vapor in equilibrium with its liquid state at a given temperature.
