🎓 Higher Tier: Gas Laws and Calculations
For a fixed mass of gas at constant volume, the pressure law states:
p₁/T₁ = p₂/T₂
(where T is in Kelvin)
Worked example: A gas at 300 K has pressure 100,000 Pa. What is the pressure at 600 K (constant volume)?
p₂ = p₁ × T₂/T₁ = 100,000 × 600/300 = 200,000 Pa
Pressure and volume (constant temperature):
p₁V₁ = p₂V₂
Compress a gas (reduce V) → particles hit walls more often → pressure increases. Used in syringes, bicycle pumps, and car engines.
