Which of the statements are evidence that gases do not always behave ideally? When two gases are mixed, they follow Dalton's law of partial pressures. It is impossible to compress a gas enough so that it takes up no volume. CO₂ gas becomes dry ice (solid CO₂) at 1 atm and -78.5 °C. At 4 K and 1 atm, helium is a liquid.
