2. Pressure and temperature are directly related
If temperature increases, pressure increases
If temperature decreases, pressure decreases.
Why?
Temperature affects kinetic energy
More kinetic energy= more collisions = more
pressure
Animation
3. P1/T1 = P2/T2
Volume must be held constant
Temp. must be in Kelvin
A balloon at 293 K and 1 atm is heated to 324K.
What is the pressure inside the balloon?
A can has a pressure of 2.5 atm at 36oC. If we cooled
the can to 100 C what would be the new pressure?
