Announcments:
Objectives: Determine how the pressure, temperature &
volume of a gas will change when one or more factors are
changed
Warm-up: 29.86 grams of Lead (II) iodide is produced when
KI is combined with lead (II) nitrate. What masses of KI &
lead (II) nitrate are needed so that each are completely
consumed?

Temperature scales...

Tc = (5/9)*(Tf-32) solve for Tf
But for gas laws...always stick with "Kelvins"
pressure units & equivalents
Thinking about graphs and relationships
Lab Discussion, STP
Combined gas law
Ideal gas law
Universal gas constant

Working with gas laws (problem set)
