When must temperature values in gas law calculations be expressed in kelvin units?

Question

Quizplus · Accepted Answer

Temperature values in all gas law calculations must be expressed in kelvin units because the scale is based on absolute zero, at which point gas particles completely stop moving. The Kelvin scale is used to determine the kinetic energy of gas particles, which is directly proportional to the temperature. Therefore, for accurate calculations, temperature values must be expressed in kelvin units.
