In order for the relationship between temperature and volume described by Charles' Law to work, what must be the unit of temperature?
Answer (1)
For Charles' Law to work correctly, the temperature must be in Kelvin (K). This is because Charles' Law describes a directly proportional relationship between temperature and volume, and Kelvin is an absolute temperature scale where 0 K represents absolute zero (the point where molecular motion stops). Using Celsius or Fahrenheit would not work properly, as they include negative values, which could lead to incorrect calculations.
