- 1. Multiple ChoiceDalton's Law states...that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gaseshow gases tend to expand when heatedthat the density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas.
