A fixed quantity of gas at 25°C exhibits a pressure of 724 torr and occupies a volume of 5.90 L.
(a) Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.71 atm while the temperature is held constant.
(b) Use Charles's law to calculate the volume the gas will occupy if the temperature is increased to 159°C while the pressure is held constant.
