A certain gas is present in a 15.0 L cylinder at 4.0 atm pressure. If the pressure is increased to 8.0 atm, the volume of the gas decreases to 7.5 L. Find the two constants ki, the initial value of k, and kf, the final volume of k, to verily whether the gas obeys Boyle's law.
Express your answers to two significant figures separated by a comma.
If a certain gas occupies a volume of 12 L when the applied pressure is 6.0 atm, find the pressure when the gas occupies a volume of 3.0L.
Express your answer to two significant figures, and include the appropriate units.
