Gay-Lussac’s Law Temperature-Pressure relationships

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

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?
