Which has stronger attractions among its submicroscopic particles: a solid at 25°C or a gas at 25°C?
A) The attractions among the submicroscopic particles of the solid must be stronger than the attractions among the particles of the gas.
B) The submicroscopic particles of the gas are moving faster. This means that they have more energy, which means that the attractions among them must be stronger.
C) The attractions among the submicroscopic particles of the solid are much stronger—so much stronger that they hold the particles of the solid absolutely still.
D) The temperatures of these two materials are the same, which means that the attractions among their submicroscopic particles are also of the same strength.
