The document discusses Gay-Lussac's Law, formulated by Louis Joseph Gay-Lussac, which describes the relationship between the pressure and temperature of a gas. It provides both theoretical background and practical examples of how Gay-Lussac’s Law applies to real-world scenarios involving gases.
GAY LUSSAC’S LAW
Gay Lussac’s law: Louis Joseph Gay Lussac
❖ P and T
❖ The pressure exerted by a gas is directly related to the kelvin temperature
❖ V and n are constant
❖ P1/T1=P2/T2
❖ Sample 1
➢ A 30.0 L sample of nitrogen inside a rigid, metal container at 20.0C is placed
inside an oven whose temp is 50.0C. The pressure inside the containe at 20C wast at
3 atm. What is the pressure of the nitrogen after its temperature is increased to 50C
Given:
P1= 3.00 atm
P2= ?
T1= 20.0 °C
T2 = 50.0 °C
➢ Solution:
P1/T1=P2/T2
3.00 atm/293 K = P2/323 K
P2=3.31 atm
❖ Sample 2
➢ Determine the pressure change when a constant volume of gas at 1 atm is heated
from 20C to 30C
Given:
P1= 1.00 atm
P2=?
T1= 20 °C
T2= 30.0 °C
➢ Solution:
P1 / T1 = P2 / T2
1.00 atm / 293 = x / 303
P2= 1.03 atm
Unit Relationship to 1 atm
Atmosphere (atm) 1 atm
Millimeter of mercury (mmHg) 760mmHg
