2.cold air is heavier because it is more dence. 3.cold air has higher air pressure because it's molecules are closer together

Temperature also makes changes in air pressure. In cold air, the molecules are more closely packed together than in warm air, so cold air is more dense than warm air. Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink.
