General Formulas and Concepts:
<u>Chemistry - Gas Laws</u>
Gay Lussac Law -
- P₁ is Pressure 1
- T₁ is Temperature 1 in Kelvin
- P₂ is Pressure 2
- T₂ is Temperature 2 in Kelvin
Explanation:
<u>Step 1: Define</u>
P₁ = 1.40 atm
T₁ = 12°C
P₂ = unknown
T₂ = 35°C
<u>Step 2: Identify Conversions</u>
1 atm = 760 mmHg
K = °C + 273.15
<u>Step 3: Convert</u>
P₁ = 1.40 atm = 1064 mmHg
T₁ = 12°C = 285.15 K
T₂ = 35°C = 308.15 K
<u>Step 4: Find P₂</u>
- Substitute:
- Cross-multiply:
- Multiply:
- Isolate P₂:
- Divide:
- Rewrite:
<u>Step 5: Check</u>
