In Boyle's law volume and pressure vary inversely, whereas in Charles' law, volume and pressure vary directly.
Consider an example, if the pressure in Boyle's law is doubled from 1.0 atmospheres to 2.0 atmospheres with an original volume of 1.0 liter, the new volume will be 0.50 liters.
This in accordance with Boyle's law which states that the product of the initial pressure and volume is equal to the product of the final pressure and volume.
P1V1 = P2V2
Now compare this to Charles ' law which states that the product of the initial volume and the final temperature is equal to the product of the final volume and initial temperature.
Remember that all temperatures must be calculated in kelvin
If the initial temperature of 273 K is doubled to 546 K,
then a initial volume of 1.0 liter is also doubled, with a final volume of 2.0 liters.
If the te
