Find V2
Find T2
Formula
V1 / T1 = V2 / T2, where V is volume and T is absolute temperature in Kelvin at constant pressure.
Frequently Asked Questions
What is Charles's Law?
Charles's Law states that the volume of an ideal gas is directly proportional to its absolute temperature when pressure is held constant: V1/T1 = V2/T2.
Why must temperature be in Kelvin?
Kelvin is an absolute temperature scale starting at absolute zero. Using Celsius or Fahrenheit would produce incorrect results because they can be zero or negative, breaking the proportional relationship.
