Charles's Law
Charles's Law states that the volume of a gas is directly proportional to its absolute temperature, assuming constant pressure. Mathematically:
V₁/T₁ = V₂/T₂
Where:
* V₁ = Initial volume
* T₁ = Initial temperature (in Kelvin)
* V₂ = Final volume
* T₂ = Final temperature (in Kelvin)
1. Convert Temperatures to Kelvin:
* -45°C + 273.15 = 228.15 K
* 45°C + 273.15 = 318.15 K
2. Set up the Equation:
3.8 L / 228.15 K = V₂ / 318.15 K
3. Solve for V₂ (the final volume):
V₂ = (3.8 L * 318.15 K) / 228.15 K
V₂ ≈ 5.3 L
Therefore, the helium will occupy approximately 5.3 liters at 45°C.
