Charles’ Law: The volume of a fixed mass of gas varies directly with the Kelvin temperature at constant pressure.
Mathematically, it is expressed as
V/T = k
Where k is a constant, V is volume and T is the Kelvin temperature.

4. Sample Charles’ Law Problem V1/T1 = V2/T2
Calculate the new temperature of a gas when 2.50 L at 293 K is compressed to 1.00 L at constant pressure.

5. Answer: 𝑉 1 𝑇 1 = 𝑉 2 𝑇 2
Step 1: 2.50L 293K = 1.0L T 2
Step 2: L K = 1.0L T 2
Step 3: T 2 × L K =1.0L
Step 4: T 2 = 1.0L L K
T 2 =117K

6. Sample Charles’ Law Problem V1/T1 = V2/T2
Oxygen gas is at a temperature of 40 C when it occupies a volume of 2.3 liters. To what temperature should it be raised to occupy a volume of 6.5 liters?

7. Sample Charles’ Law Problem V1/T1 = V2/T2
