According to Boyle, pressure and volume of a confined gas are INVERSELY proportional, and according to Charles, the volume of a gas at constant pressure is DIRECTLY proportional to its Kelvin temperature.
Answer: Inversely, directly
Explanation: 1) Boyle's Law: The law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
[tex]P\propto \frac{1}{V}[/tex] (At constant temperature and number of moles)
2) Charles' Law: The law states that volume is directly proportional to the temperature of the gas in Kelvin at constant pressure and number of moles.
[tex]V\propto T[/tex] (At constant pressure and number of moles)
