Cum se calculează Charles's Law
Ce este Charles's Law?
Charles's Law states that at constant pressure, the volume of an ideal gas is directly proportional to its absolute temperature (in Kelvin). V₁/T₁ = V₂/T₂. Heating a gas at constant pressure makes it expand.
Ghid pas cu pas
- 1Always convert temperatures to Kelvin: K = °C + 273.15
- 2Record V1 and T1; identify desired T2
- 3V2 = V1 × T2 / T1
- 4Pressure must remain constant
Exemple rezolvate
Intrare
V1=5L at T1=300K · heated to T2=450K
Rezultat
V2 = 7.5L
5×450/300=7.5L
