Relationship between pressure and temperature Volume is held constant Gay-Lussac Law Notes Relationship between pressure and temperature Volume is held constant

Gay-Lussac’s Law If the temperature of a gas increases, the pressure also increases This is a direct relationship between T and P P1 = P2 T1 T2

Gay-Lussac’s Law __1.00__ 298 _P2_ 318 = P2 = 1.10 atm Example: If a gas at 25.0ºC and 1.00 atm is heated to 45.0ºC, then what is the new pressure? Assume constant volume __1.00__ 298 _P2_ 318 = P2 = 1.10 atm
