Pressure & Temperature
P / T = constant
For a fixed mass of gas at constant volume: P₁/T₁ = P₂/T₂ (T must be in Kelvin)

Instructions:
- Move the Temperature slider to heat or cool the sealed container
- Observe the animated particles moving faster at higher temperatures
- Record data points at 5–6 different temperatures
- Check the P/T column — it should stay approximately constant
- The P–T graph should be a straight line through the origin
- Important: Temperature must be in Kelvin (K = °C + 273)
