* **The density of a gas is constant as long as its temperature remains constant:** **False**. Density depends on both temperature *and* pressure. While a constant temperature is part of the equation, if the pressure changes, the density will also change.<br /><br />* **Gases diffuse into each other and mix almost immediately when put into the same container:** **True**. Gases are characterized by rapid, random motion of their particles, leading to quick diffusion and mixing.<br /><br />* **A real gas approaches ideal behaviour under conditions when P is high and T is low:** **False**. Ideal gas behavior is approached at *low* pressure and *high* temperature. At high pressure and low temperature, intermolecular forces and the volume of the gas particles themselves become significant, deviating from the ideal gas model.<br />
