Venus has a runaway greenhouse effect.
gas- less particles move fast and freely, not contained
liquid- particles move a bit slower, more particles
solid- particles barely move, many particles in a confined space
Chemical properties can only be tested if you change the substance
Which two conditions can limit the usefulness of the kinetic-molecular theory in describing gas behavior? ... Increasing pressure is causing a smaller change in gas volume. The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressured and temperature.
