Charles’ Law can calculate the volume of a substance if you already know the gas of this substance about its temperature. In this case, we know that the substance is argon and it has a volume of one milliliter with a ratio of the volume of 0.43 milliliters at two hundred ninety-nine Kelvin which is the same as four hundred twenty-two degrees Celsius.
The formula for Charles’s Law is considered to be an ideal gas law. It is Vi/Ti = Vf/Tf. This means that the Vi stands for initial volume, Ti stands for initial absolute temperature. The Vf stands for the final volume, and the Tf stands for the final absolute temperature. In this case, when you plug in the numbers, it would be 422 C.
