Select the statement that is true concerning the states of matter of a(n) substance. In the solid and liquid phase of a substance the molecules/atoms are close togetherIn a gas phase of the substance, if the pressure is increased, the volume of the gaseous substance also increases at constant temperature. attractive forces will dominate in the gas phase for the substance due to the high rate of collisions.the volume of the liquid form of the substance is governed by the following equation: pV = nRT.the substance's density will always be greater in the solid phase.
