How did Charles's law lead to the concept of an absolute scale of temperature?

उत्तर
The temperature scale with its zero at -273°C and where each degree is equal to the degree on the Celsius scale is called the absolute scale of temperature.
The temperature of -273°C is called absolute zero. Theoretically, this is the lowest temperature which can never be reached. All molecular motion ceases at this temperature.
The temperature of -273°C is called absolute zero.
V = V° `((273 + "t")/273)`
Volume at - 273°C = V° `((273 - 273)/273) = 0`
