1. Pressure and Temperature Law

2. Temperature and Pressure
What would happen to the pressure in a sealed container (i.e. volume remains constant) if heat is added?
Graph the following data:
Temperature (K)
Pressure (kPa)
129
111
301
242
403
323
501
429
601
517
704
613

3. Pressure and Temperature Law
Pressure increases proportionally as temperature increases, provided volume and amount remain constant.
Pressure is directly proportional to temperature (in Kelvins)
P  T
A direct relationship
P = kT
P = k T
P1 = P2
