Carbon dioxide is a weak acid gas with a slightly pungent odor at high temperatures. Carbon dioxide cannot exist as a liquid at atmospheric pressure. When the temperature and pressure are above the triple point, but below 31.1 C, the liquid and gas of carbon dioxide are in equilibrium in a closed container. Carbon dioxide is non-flammable and, in the presence of water, can corrode some common metals. Carbon dioxide cannot sustain life.
