Achemist investigates the relationships among temperature, volume, and pressure of a gas. the chemist discovers that for every doubling of the pressure on a gas, its volume is halved. she also discovers that for every doubling of the temperature of the gas, its volume doubles. which two conclusions about the behavior of gases does this allow the chemist to reach? a. volume varies inversely with pressure; volume varies inversely with temperature. b. volume varies directly with pressure; volume varies directly with temperature. c. volume varies directly with pressure; volume varies inversely with temperature. d. volume varies inversely with pressure; volume varies directly with temperature.
